I-Polyvinyl Chloride (PVC) resin yepayipi
I-Polyvinyl Chloride (PVC) resin yepayipi,
I-PVC yepayipi yokudonsa amanzi, I-PVC Pipe Raw Material, PVC resin for Hose, I-PVC resin yokunisela,
I-Polyvinyl Chloride (PVC) iyi-resin eqondile ye-thermoplastic ekhiqizwa yi-polymerization ye-vinyl chloride monomer.Ngenxa yomehluko wezinto ezingavuthiwe, kunezindlela ezimbili zokwenza inqubo ye-vinyl chloride monomer calcium carbide kanye nenqubo ye-petroleum.I-Sinopec PVC yamukela inqubo yokumiswa okubili, ngokulandelana kwayo kusukela ku-Japan Shin-Etsu Chemical Company kanye ne-American Oxy Vinyls Company.Umkhiqizo unokumelana nokugqwala kwamakhemikhali okuhle, indawo enhle kakhulu yokufaka ugesi kanye nokuzinza kwamakhemikhali.Ngokuqukethwe okuphezulu kwe-chlorine, izinto ezisetshenziswayo zinokubambezeleka okuhle komlilo kanye nezakhiwo zokuzicisha.I-PVC kulula ukuyicubungula nge-extrusion, ukubumba umjovo, i-calendering, ukubunjwa kokushaywa, ukucindezela, ukubunjwa kwe-cast kanye nokubumba okushisayo, njll.
Isicelo
I-PVC ingenye yezinhlaka ze-thermoplastic ezisetshenziswa kakhulu.Ingasetshenziselwa ukwenza imikhiqizo enobulukhuni obuphezulu namandla, njengamapayipi nokufakwa, iminyango enephrofayili, amafasitela namashidi okupakisha.
Ingakwazi futhi ukwenza imikhiqizo ethambile, efana namafilimu, amashidi, izintambo zikagesi nezintambo, amabhodi aphansi kanye nesikhumba sokwenziwa, ngokufaka ama-plasticizers.

I-Polyvinyl Chloride (PVC) ingenye yezinto ezisetshenziswa kakhulu ze-thermoplastic ezivamile ezimbonini eziningi.Amapayipi e-PVC abonisa ikhwalithi ehlukile futhi engaguquguquki enezakhiwo ezifanayo okwenza kube ukukhetha okuncanyelwayo kwabakhi bezindlu nezindlu zangokwezifiso.Imelana kakhulu nama-acids, alkalis, alcohols, nezinye izinto eziningi ezigqwalayo.Izinhlelo ze-PVC zilula, ziyavumelana nezimo futhi ziqinile, futhi zinikeza ukumelana nokugqwala okukhethekile.Ngenxa yalezi nezinye izici zekhwalithi ephezulu ye-thermoplastic enobunjiniyela, ukonga okungatholakala ekufakweni kokuqala kanye nezindleko zokuyilungisa eziqhubekayo zinkulu.Ipayipi le-PVC lilungele ukusetshenziswa okuningi okuhlanganisa ukusatshalaliswa kwamakhemikhali kanye nokukhipha amanzi, ukuhlanzwa kwamanzi namanzi angcolile, amapayipi esevisi, amasistimu okunisela, ukuqoqwa kwemfucuza nezinye izinto eziningi ezisebenza ezimbonini ezibandakanya ukudluliswa koketshezi olubolayo.Isilinganiso sokucindezela siyahlukahluka ngeshejuli, usayizi wepayipi nezinga lokushisa.
