Intshayelelo
I-PVC isebenza njengeplastiki yendalo yonke enesivuno esikhulu kunye nobubanzi besicelo emhlabeni.Isetyenziswe ngokubanzi kwimiba efana nemathiriyeli yokwakha, imveliso yemizi-mveliso, imibhobho esetyenziswa mihla le, imathiriyeli yokutywina, iintsinga, njl. njl. IPVC ibonisa iipropati ezininzi ezigqwesileyo ukuze zisetyenziswe ngokubanzi kuwo omabini amacandelo oshishino kunye noluntu.Nangona kunjalo, i-PVC resin yeyezinto ezinqabileyo.Isigaba salo seglasi esiqhubekayo asikwazi ukuthintela ukwandiswa okukhulu kweentanda phantsi koxinzelelo kwaye ekugqibeleni yenze izithuba kunye nokuqhekeka okuqhekekileyo.Ke ngoko, uhlobo olunjalo lwemathiriyeli lubonisa ukuxhathisa impembelelo embi.Nangona kunjalo, le ntsilelo inokoyiswa ngokongezwa kwesiguquli sempembelelo kwizinto zePVC ngexesha lokwenziwa kwazo kunye nenkqubo yokubumba.
Izilungisi zempembelelo ezilungileyo kufuneka zibonakaliswe ngokulandelayo iimpawu ezigqwesileyo:
(1) Ubushushu obuphantsi ngokwentelekiso be-vitrification Tg;
(2) Ukuhambelana kwempembelelo yokuguqula ngokwayo kunye ne-PVC resin;
(3) Ukulinganisa i-Viscosity yempembelelo yokuguqula i-PVC;
(4) Akukho siphumo esibi esicacileyo kwiipropati ezibonakalayo kunye neempawu ezibonakalayo kunye nezomatshini zePVC;
(5) Ukumelana nemozulu elungileyo kunye nepropathi yokudumba.
Izilungisi zempembelelo ezixhaphakileyo ze-PVC enzima ikakhulu zigubungela i-chlorinated polyethylene (CPE), i-acrylate (ACR), i-ethylene-vinyl acetate copolymer (EVA), i-methyl methacrylate-butadiene-styrene ternary graft copolymer(MBS) kunye ne-acrylonitrile-butadiene-styrene-ABS ).Phakathi kwazo, isilungisi sempembelelo ye-polyethylene eneklorini sele isetyenziswe kakhulu e-China kwaye i-acrylate nayo yamkelwa ngokwandayo ngenxa yeempawu zayo ezintle.Kuye kwaba yinkxalabo ngokubanzi indlela yokuphucula ukuchasana kwempembelelo kunye nokuququzelela i-extrusion yeplastiki.
Imveliso yethu ye-AIM i-ADX-600 inokutshintsha i-CPE kunye ne-MBS.Ingaphucula kakhulu ubumanzi kunye nokuguqulwa kwe-thermal ye-PVC yokunyibilika kwaye ngaloo ndlela iququzelele iPVC yeplastiki.Iimveliso ezinesiphumo zibonisa amandla empembelelo ephezulu kunye nokumelana nemozulu elungileyo, uzinzo kunye nokulungiswa kwepropathi enomgangatho ogudileyo, omhle kunye nocwebezelayo.Okulandelayo, siye sahlalutya i-ACR, i-CPE kunye ne-MBS kule miba ilandelayo.
I. Indlela yokuThwatshazwa yi-PVC Impact Modifiers
I-Chlorinated polyethylene (CPE) isebenza njengeemolekyuli zomgca ezisasazwe kwi-matrix ye-PVC kwifomu yenethiwekhi.Umgaqo wokumelana nempembelelo kukwenza inethiwekhi ye-elastic kwi-PVC matrix imathiriyeli ukwenzela ukuxhathisa impembelelo yangaphandle.Uthungelwano olunjalo luthanda ukonakala phantsi kwamandla obunzima.Oku kuya kuxhokonxa ukutyibilika komdibaniso kwi-engile ye-30 ° ukuya kwi-45 ° ukusuka kwicala le-tensile, ngaloo ndlela yenze ibhendi yokucheba, ifunxa isixa esikhulu samandla oguquko, kunye nokuphucula ukuqina kwenkqubo yokudibanisa.Utshintsho kwimveliso yoxinzelelo lwezinto phantsi kwamandla angaphandle luboniswa kula manani alandelayo.
I-ACR kunye ne-MBS zezohlobo lwe-"core-shell" ye-copolymer impact modifier.Undoqo wayo usebenza njenge-elastomer edityanisiweyo ephantsi, edlala indima ephambili ekomelezeni ukuqina kunye nokuxhathisa impembelelo.Igobolondo layo lisebenza njengepolymer ephezulu yemolekyuli enobushushu obuphezulu be-vitrification, edlala indima ephambili ekukhuseleni i-rubber core kunye nokuphucula ukuhambelana ne-PVC.Olu hlobo lwamasuntswana okulungisa kulula ukwahlulwa kwaye lunokusasazwa ngokulinganayo kwi-PVC matrix ukuze yenze "isiqithi-selwandle" isakhiwo.Xa izinto eziphathekayo zixhomekeke kwimpembelelo yangaphandle, iinqununu zerubha ezinemodyuli ephantsi zixhomekeke kwi-deformation.Ngelo xesha, i-de-bonding kunye ne-cavity yenziwa njengoko izinto eziphathekayo ziqhutyelwa yi-PVC deformation kunye ne-modulus ephezulu.Ukuba loo mingxunya yakhelwe kufutshane ngokwaneleyo, umaleko we-matrix phakathi kwamasuntswana erabha unokuvelisa kwaye wongeze ukuqina kwemathiriyeli.Umgaqo-okumelana nempembelelo uboniswe kumzobo ongezantsi.
I-CPE, i-ACR kunye ne-MBS zibonisa ubuntununtunu obahlukeneyo kumandla omatshini ngenxa yeendlela zabo ezahlukeneyo zokuqina.Ngexesha lokucubungula, iincinci ze-ACR kunye ne-MBS zisasazwa kwi-matrix ye-PVC ngokusebenzisa isenzo sokucheba, ukwenza "isiqithi-solwandle" isakhiwo kwaye ngaloo ndlela siphucula ukuqina kwezinto.Nokuba amandla okusebenza enyuka ngakumbi, olu lwakhiwo aluyi kuphazamiseka ngokulula.Eyona mpembelelo igqwesileyo inokuzalisekiswa kuphela njengoko isilungisi se-CPE kunye ne-PVC zidityaniswe kwisakhiwo sothungelwano esifakela amasuntswana aphambili ePVC.Nangona kunjalo, esi sakhiwo sothungelwano sinokuchaphazeleka ngokulula ngenxa yotshintsho kugxininiso lokucubungula.Ngoko ke, inovakalelo kugxininiso lokucubungula kwaye lusebenza kuluhlu oluncinci lokucubungula.
