Yazisa:
I-Polyvinyl chloride resin, eyaziwa ngokuba yi-PVC resin, yi-polymer compound eyenziwe ipholymerized ukusuka kwi-vinyl chloride monomer (VCM).Ngenxa yeepropathi zayo eziguquguqukayo nezinamandla, i-PVC resin isetyenziswa kakhulu kumashishini ahlukeneyo, kubandakanya nokhathalelo lwempilo.Kule bhlog, siza kuphonononga ukubaluleka kwe-PVC resin njengekhompawundi yezonyango kwaye siqonde ukuba izinto ezifana nenkqubo yepolymerization, iimeko zokusabela, ukubunjwa kwe-reactant kunye nezongezo zichaphazela njani ukusebenza kwayo.

Polyvinyl chloride resin: ukujonga ngokusondeleyo
I-resin ye-PVC yenziwe nge-polymerizing vinyl chloride monomer, inkqubo eyenza imixokelelwane emide yezinto zokwakha i-CH2-CHCl.Iqondo lepolymerization, ngokuqhelekileyo i-590 ukuya kwi-1500, inceda ukwandisa amandla kunye nokuqina kwezinto.

Izicelo kwintsimi yezonyango
I-resin ye-PVC isetyenziswa ngokubanzi kushishino lwezonyango ngenxa yeempawu zayo ezintle.Ngokuqhelekileyo isetyenziselwa ukuvelisa izixhobo zonyango ezifana ne-intravenous tubing, iingxowa zegazi, i-catheters kunye neeglavu zotyando.Ukuguquguquka kwe-resin ye-PVC, ukucaca, kunye nokumelana nemichiza kuyenza ibe yinto efanelekileyo kwizicelo zonyango.

Izinto ezichaphazela ukusebenza kwe-PVC resin
Ukusebenza kwe-PVC resin kuya kuhluka ngokuxhomekeke kwizinto ezahlukeneyo.Inkqubo yepolymerization idlala indima ebalulekileyo ekumiseleni ubunzima bemolekyuli kunye neqondo lepolymerization.Iimeko zokusabela, ezifana nobushushu kunye noxinzelelo, nazo zichaphazela iimpawu zemveliso yokugqibela.Ukongeza, ukubunjwa kwe-reactants kunye nokongezwa kwezongezo kunokuphucula ngakumbi iipropati ze-resin ukuhlangabezana neemfuno ezithile zonyango.

Izongezo kwi-PVC resin
Izongezo zihlala zongezwa kwintlaka yePVC ukukhulisa iipropathi ezithile.Ngokomzekelo, i-plasticizers inokunyusa ukuguquguquka, ukwenza izinto ezifanelekileyo ngakumbi kwizicelo ezifuna ukunyakaza kunye nokugoba.Ukongeza i-stabilizers kunokonyusa ukumelana nobushushu kunye nokumelana nokukhanya kwe-resin kunye nokuqinisekisa ubomi bayo benkonzo.Ezinye izongezo zibandakanya ukuguqulwa kweempembelelo, ii-lubricants kunye nezihluzi, zonke ezinceda ukuphucula ukusebenza kunye nokusetyenziswa.

ukuququmbela:
I-Polyvinyl chloride resin, okanye i-PVC resin, iyaqhubeka ibe yinto ebalulekileyo kwishishini lezonyango.Ukuguquguquka kwayo, amandla kunye nokuchasana kweekhemikhali kwenza kube yinto ekhethiweyo kwizixhobo zonyango.Ukuqonda impembelelo yezinto ezifana nenkqubo ye-polymerization, iimeko zokusabela, ukubunjwa kwe-reactant kunye nezongezo zibalulekile ekuveliseni ii-resin ze-PVC ezineempawu ezifunwayo.Njengoko iteknoloji iqhubela phambili, uphuhliso olongezelelweyo kwi-PVC resin ngokungathandabuzekiyo luya kubumba ikamva lezinto ezintsha zonyango, ekugqibeleni luzuzisa izigulane kunye nababoneleli bezempilo.
