Ekwakhiweni kwanamuhla, ubunjiniyela bomasipala, kanye nasemikhakheni eminingi yezimboni, amapayipi e-PVC adlala indima ebaluleke kakhulu. Ukusetshenziswa kwawo okubanzi kuzuza ekusebenzeni kwawo okuhle kanye nenqubo yokukhiqiza evuthiwe. Ngakho-ke, iyini ngempela inqubo yokukhiqiza amapayipi e-PVC?
Amapayipi e-PVC akhiqizwa ngenqubo yokukhipha izinto zokusetshenziswa ze-PVC futhi ngokuvamile anamathela ezinqubweni ezivamile zokusebenza kokukhipha amapayipi okujwayelekile: Okokuqala, ama-pellet noma ufulawa wezinto zokusetshenziswa ufakwa emanzini.I-extruder ye-PVC enama-screw amabili. Ngemuva kwalokho, ukuncibilikisa nokushisa kwenziwa ezindaweni eziningi zokukhipha izinto. Le nqubo ibonakala ilula uma iqhathaniswa, kodwa empeleni, ihilela ubuchwepheshe obuyinkimbinkimbi kanye nezixhumanisi zenqubo, kanye nochungechunge lwemishini yobungcweti kanye nemigqa yokukhiqiza, phakathi kwayo kukhona eminye emele embonini yokukhipha izinto ngepulasitiki yaseShayina.
Emgqeni wokukhiqiza wamapayipi e-PVC, i-extruder ngokungangabazeki iyimishini eyinhloko. I-extruder yenza umsebenzi obalulekile wokuguqula izinto zokusetshenziswa zibe amapayipi akhiwe kuyo yonke inqubo yokukhiqiza. Uma sibheka imboni ye-plastic extrusion yaseShayina njengesibonelo, amabhizinisi amaningi abelokhu ehlola futhi esungula izinto ezintsha kulo mkhakha. Isibonelo, uBlesson, umkhiqizi we-extruder waseShayina odumile, unolwazi olucebile kanye nempumelelo evelele ocwaningweni, ekuthuthukisweni nasekukhiqizweni kwe-extruder.Umshini wokukhipha i-extruder kaBlessonIfektri isebenzisa ubuchwepheshe nezinqubo ezithuthukisiwe, kanti ama-extruder akhiqizwayo anezinzuzo ezibalulekile maqondana nokunemba, ukuzinza, kanye nokusebenza kahle kokukhiqiza, okunikeza isiqinisekiso esiqinile sokukhiqizwa kwamapayipi e-PVC asezingeni eliphezulu.
Uma i-extruder ye-PVC twin screw isebenza, isakhiwo sayo se-screw sakhiwe ngobuhlakani. Lezi zikulufo ezimbili ziyasebenzisana ukuze zivumele izinto zokusetshenziswa ukuthi ziqhubekele phambili ngokulinganayo ngaphansi kokucindezelwa kwezikulufo futhi kancane kancane ziqedele izinqubo zokushisa nokuncibilikisa ezindaweni eziningi. Endaweni yokuqala, izinto zokusetshenziswa zivame ukushiswa ngaphambi kwesikhathi ukuze ama-pellet noma i-powder iqale ukuthamba, okwenza kube lula ukucubungula okulandelayo. Njengoba izinto zokusetshenziswa zihanjiswa yizikulufo endaweni yesibili, izinga lokushisa lizokhuphuka kakhulu. Ngalesi sikhathi, i-PVC iqala ukuncibilika kancane kancane futhi yakhe ukuncibilika okunoketshezi oluthile. Kule nqubo, uhlelo lokushisa lwe-extruder ludlala indima ebalulekile. Ukulawula izinga lokushisa okunembile kungaqinisekisa ukuthi izinto zokusetshenziswa ze-PVC zincibilika ekushiseni okufanele, kugweme umthelela ekhwalithini yamapayipi ngenxa yokushisa okuphezulu kakhulu noma okuphansi. Isibonelo, uma izinga lokushisa liphezulu kakhulu, kungabangela ukubola kwe-PVC, okuholela ezinkingeni ezifana nokushintsha kombala kanye nokuqhekeka kwamapayipi; kanti uma izinga lokushisa liphansi kakhulu, ukuncibilika ngeke kwanele, futhi umphumela wokwakheka kwamapayipi uzoba mubi, kanye neziphambeko ezingaba khona njengobuso obungalingani kanye nesakhiwo sangaphakathi esingalingani.
Ngemva kokuba izinto zokusetshenziswa ze-PVC zincibilikisiwe ku-extruder, zingena esigabeni sokwakheka. Kulesi sigaba, ukuncibilika kwe-PVC kukhishwa ngesikhunta esithile ukuze kwakheke isimo sokuqala sepayipi. Umklamo kanye nokukhiqizwa kweisikhuntazinomthelela omkhulu ekhwalithini yokugcina yepayipi le-PVC. Izikhunta zekhwalithi ephezulu zingaqinisekisa ukunemba kobukhulu, ukufana kobukhulu bodonga, kanye nokushelela kobuso bamapayipi. Njengomkhiqizi we-extruder waseShayina ochwepheshe, i-Blesson itshale imali eningi yezinsiza zocwaningo nentuthuko kuisikhuntaukuklama nokukhiqiza, kanye nezikhunta ezikhiqizayo kungahlangabezana nezidingo zokukhiqiza zamapayipi e-PVC anezincazelo ezahlukene kanye nezimo zokusetshenziswa ezahlukene.
Ngemva kokukhishwa kwamapayipi, kudingeka apholiswe futhi alinganiswe. Le nqubo ivame ukufezwa ngamathangi amanzi okupholisa noma amadivayisi okupholisa umoya. Amanzi okupholisa asemanziniithangi lamanzi okupholisakuzosusa ukushisa kwamapayipi, kuwenze aphole futhi abe nobukhulu obusheshayo. Ukulawula isivinini sokupholisa nakho kubalulekile. Uma isivinini sokupholisa sishesha kakhulu, kungabangela ukucindezeleka kwangaphakathi emapayipini, kuthinte izakhiwo zawo zemishini; kanti uma isivinini sokupholisa sihamba kancane kakhulu, kuzonciphisa ukusebenza kahle kokukhiqiza futhi kungabangela ukuthi amapayipi aguge ngesikhathi senqubo yokupholisa.
Ngaphezu kwezixhumanisi eziyinhloko ezingenhla, inqubo yokukhiqiza amapayipi e-PVC ihlanganisa nezinqubo ezifanaiyunithi yokuthuthafuthiukusika. Iyunithi yokudonsa inesibopho sokudonsa amapayipi akhishwe phambili ngesivinini esingaguquki ukuqinisekisa ukuqhubeka nokuqina kokukhiqizwa kwamapayipi. Isivinini seyunithi yokudonsa siyadingeka ukuze sihambisane nesivinini sokudonsa. Uma isivinini sokudonsa sishesha kakhulu, amapayipi azokwelulwa futhi abe mancane; kanti uma isivinini sihamba kancane kakhulu, amapayipi azonqwabelana, okuthinta ukusebenza kahle kokukhiqiza. Idivayisi yokusika inquma amapayipi abe imikhiqizo eqediwe ngokuya ngobude obubekiwe. Kweminye imigqa yokukhiqiza enezinga eliphezulu lokuzenzakalela, inqubo yokusika ingafinyelela ukusika okuqondile okuphezulu, kunciphisa amaphutha abangelwa ukusebenza ngesandla.
Embonini yokukhipha amapayipi epulasitiki eShayina, abakhiqizi be-extruder yepulasitiki yaseShayina abanjengoBlesson bahlala bekhuthaza intuthuko yale mboni. Abagcini nje ngokusungula izinto ezintsha kwezobuchwepheshe bokukhiqiza imishini kodwa futhi benza ucwaningo olujulile mayelana nokuklama kanye nokwenza ngcono imigqa yokukhiqiza. Isibonelo, ngokusebenzisa ukulungiswa okuhlelekile kwe-extruder, i-extrusion die, uhlelo lokupholisa, i-haul off unit, kanye ne-cutter, ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo wayo yonke.Umugqa wokukhiqiza ipayipi le-PVCzithuthukisiwe. Okwamanje, ngokushintsha okuqhubekayo kwesidingo semakethe, laba bakhiqizi bacwaninga ngenkuthalo futhi bathuthukisa izinhlobo ezintsha zemishini yokukhipha izinto kanye nemigqa yokukhiqiza ukuze bahlangabezane nezindinganiso zokukhiqiza eziphakeme kanye nezidingo zohlelo lokusebenza eziyinkimbinkimbi.
Kusukela ekukhetheni nasekuphatheni izinto zokusetshenziswa kuya ekuncibilikeni nasekufudumaleni ku-extruder, bese kuba yizinqubo zokwakha, ukupholisa, ukudonsa, kanye nokusika, inqubo yokukhiqiza amapayipi e-PVC iyinqubo eyinkimbinkimbi futhi ebucayi. Yonke isixhumanisi idinga ukulawulwa okuqinile nokuphathwa, futhi noma yiliphi iphutha elincane lingathinta ikhwalithi yomkhiqizo wokugcina. Ngenxa yemizamo yamabhizinisi amaningi kanye nochwepheshe embonini yokukhipha ipulasitiki yaseShayina, ikakhulukazi abaholi bezimboni njengoBlesson, ngokusungula ubuchwepheshe okuqhubekayo kanye nokuthuthukiswa kwenqubo, ukukhiqizwa kwamapayipi e-PVC aseShayina nakho kuthole ukuncintisana okuqinile emakethe yamazwe ngamazwe. Kungakhathaliseki ukuthi kusekwakheni izinhlelo zokuhlinzeka ngamanzi kanye nokukhipha amanzi, ukunisela kwezolimo, noma emikhakheni yezimboni njengamakhemikhali kanye namandla kagesi, amapayipi e-PVC akhiqizwa eShayina athole ukuqashelwa kabanzi ngekhwalithi yawo ethembekile. Ngokuqhubeka kwesayensi nobuchwepheshe, kukholakala ukuthi inqubo yokukhiqiza amapayipi e-PVC izoqhubeka nokukhula futhi ithuthuke, inikele kakhulu ekwakhiweni kwengqalasizinda yomhlaba wonke kanye nentuthuko yezimboni.
Ngokuphathelene nokuvikelwa kwemvelo, njengoba kugcizelelwa kakhulu ukuvikelwa kwemvelo emphakathini, amabhizinisi okukhiqiza amapayipi e-PVC nawo ahlola njalo izinqubo zokukhiqiza eziluhlaza. Ngakolunye uhlangothi, ekukhetheni izinto zokusetshenziswa, kukhona ukuthambekela kokusebenzisa izinto ze-PVC ezinobungani nemvelo nokunciphisa ukusetshenziswa kwezithasiselo eziyingozi emvelweni. Ngakolunye uhlangothi, enkambisweni yokukhiqiza, ngokwenza ngcono imishini nezinqubo, ukusetshenziswa kwamandla kanye nokukhishwa kwemfucuza kuyancishiswa. Isibonelo, abanye abakhiqizi abaphambili basebenzisa ama-motor okonga amandla kanye nezinhlelo zokushisa, ezinganciphisa ngempumelelo ukusetshenziswa kwamandla ngesikhathi senqubo yokukhiqiza. Okwamanje, ngemfucuza ekhiqizwa ngesikhathi senqubo yokukhiqiza, amabhizinisi ahlola nezindlela zokuphinda kusetshenziswe futhi kucutshungulwe imfucuza ibe izinto zokusetshenziswa ezingaphinde zisetshenziswe ukuze kusetshenziswe kabusha izinsiza.
Ngokombono wezindlela zokuthuthukiswa kwemboni, inqubo yokukhiqiza amapayipi e-PVC izothuthuka ngokuya ngobuhlakani, ukuzenzekela, ukusebenza kahle okuphezulu, kanye nokwakha imvelo esikhathini esizayo. Imishini yokukhiqiza ehlakaniphile izokwazi ukufeza ukuzihlola nokuzilungisa, ithuthukise ukusebenza kahle kokukhiqiza kanye nokuzinza kwekhwalithi yomkhiqizo. Imigqa yokukhiqiza ezenzakalelayo izonciphisa ukusebenza ngesandla, yehlise izindleko zabasebenzi, futhi ithuthukise ukunemba kokukhiqiza. Izinqubo zokukhiqiza eziphumelelayo zizofinyeza umjikelezo wokukhiqiza futhi zithuthukise ukuncintisana kwemakethe kwamabhizinisi. Umqondo wokukhiqiza oluhlaza uzodlula yonke inqubo yokukhiqiza, okwenza ukukhiqizwa kwamapayipi e-PVC kube nobungane nemvelo futhi kube nokusimama.
