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 iinguqu zempembelelo, 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.
