Izindaba

ethula:
I-Polyvinyl chloride resin, evame ukubizwa ngokuthi i-PVC resin, iyinhlanganisela ye-polymer eyenziwe nge-polymerized kusuka ku-vinyl chloride monomer (VCM). Ngenxa yezakhiwo zayo eziguquguqukayo neziqinile, i-PVC resin isetshenziswa kabanzi ezimbonini ezahlukahlukene, kufaka phakathi ukunakekelwa kwezempilo. Kule bhulogi, sizohlola ukubaluleka kwe-PVC resin njengenhlanganisela yezokwelapha futhi siqonde ukuthi izici ezifana nenqubo ye-polymerization, izimo zokusabela, ukwakheka kwe-reactant kanye nezithasiselo kuthinta kanjani ukusebenza kwayo.

I-Polyvinyl chloride resin: ukubheka eduze
I-PVC resin yenziwa nge-polymerizing vinyl chloride monomer, inqubo eyenza amaketanga amade ezakhi zesakhiwo i-CH2-CHCl. Izinga le-polymerization, ngokuvamile elingu-590 ukuya ku-1500, lisiza ukukhulisa amandla nokuqina kwento.

Izicelo emkhakheni wezokwelapha
I-PVC resin isetshenziswa kabanzi embonini yezokwelapha ngenxa yezakhiwo zayo ezinhle kakhulu. Ivame ukusetshenziselwa ukukhiqiza izinsiza zezokwelapha ezifana ne-intravenous tubing, izikhwama zegazi, ama-catheter namagilavu ​​okuhlinza. Ukuguquguquka kwe-PVC resin, ukucaca, nokumelana namakhemikhali kuyenza ilungele ukusetshenziswa kwezokwelapha.

Izinto ezithinta ukusebenza kwe-PVC resin
Ukusebenza kwe-PVC resin kuzohluka ngokuya ngezinto ezahlukahlukene. Inqubo ye-polymerization idlala indima ebalulekile ekunqumeni isisindo samangqamuzana kanye nezinga le-polymerization. Izimo zokusabela, njengezinga lokushisa nokucindezela, nazo zithinta izici zomkhiqizo wokugcina. Ngaphezu kwalokho, ukwakheka kwama-reactants kanye nokwengezwa kwezithasiselo kungaqhubeka nokuguqula izakhiwo ze-resin ukuze kuhlangatshezwane nezidingo ezithile zezokwelapha.

Izithasiselo ku-PVC resin
Izithasiselo zivame ukungezwa ku-PVC resin ukuze kuthuthukiswe izakhiwo ezithile. Isibonelo, ama-plasticizers angandisa ukuguquguquka, okwenza izinto zifaneleke kakhulu izicelo ezidinga ukunyakaza nokugoba. Ukwengeza ama-stabilizers kungathuthukisa ukumelana nokushisa nokumelana nokukhanya kwe-resin futhi kuqinisekise impilo yayo yesevisi. Ezinye izithasiselo zihlanganisa izilungisi zomthelela, izinto zokugcoba nezihluzi, konke okusiza ukuthuthukisa ukusebenza nokusebenziseka.

Ekuphetheni:
I-Polyvinyl chloride resin, noma i-PVC resin, iyaqhubeka nokuba yinhlanganisela ebalulekile embonini yezokwelapha. Ukuguquguquka kwayo, amandla kanye nokumelana namakhemikhali kuyenza ibe yimpahla yokuzikhethela kumishini yezokwelapha. Ukuqonda umthelela wezinto ezifana nenqubo ye-polymerization, izimo zokusabela, ukwakheka kwe-reactant kanye nezithasiselo kubalulekile ekukhiqizeni ama-PVC resins anezici ezifiselekayo. Njengoba ubuchwepheshe buthuthuka, ukuthuthukiswa okuqhubekayo kwe-PVC resin ngokungangabazeki kuzololonga ikusasa lezinto ezintsha zezokwelapha, ekugcineni kuzuzise iziguli nabahlinzeki bezempilo.
