Izithambisi zizongezo eziyimfuneko kwi-PVC processing.Kwizinto zokuthambisa, imisebenzi edla ngokukhankanywa kushishino inokushwankathelwa ibe ngamanqaku amabini.Zizo: kunokunciphisa ukungqubana phakathi kwamasuntswana kunye ne-macromolecules kwi-PVC enyibilikayo ngaphambi kokunyibilika;Nciphisa ingxabano phakathi kwe-PVC yokunyibilika kunye nomphezulu woqhagamshelwano ngoomatshini beplastiki.Kwinqaku lanamhlanje, umenzi weSainuopolyethylene waxiya kukuthatha ukuba uhlalutye ukuthambisa kwangaphakathi nangaphandle kwee-lubricants ze-PVC ngokwembono yobugcisa!

1. Ukuthambisa kwangaphakathi
I-lubrication yangaphakathi ye-lubricant, ngokwe-PVC, inokuthathwa njengoluhlobo olufanayo lwezinto ezifana ne-plasticizers, idlala indima yeplastiki okanye yokuthambisa.Umahluko kukuba i-lubricant ine-polarity ephantsi kunye namatyathanga ekhabhoni amade, anciphisa kakhulu ukuhambelana phakathi kwe-lubricant kunye ne-polyvinyl chloride xa kuthelekiswa ne-plasticizers.Ngenxa yokuhambelana okuphantsi (kunye nokuhambelana okuthile) phakathi kwezithambisi kunye ne-polyvinyl chloride, kuphela isixa esincinci seemolekyuli zokuthambisa ezinokungena phakathi kwamatyathanga emolekyuli yepolymer njengeeplastiki, okwenza buthathaka umtsalane phakathi kwamatyathanga emolekyuli, kwaye ibangele ukuba ipolymer igqwethe, amatyathanga eMolekyuli Ithambekele ngakumbi ekutyibilikeni kwaye ijikelezisane, ngelixa inganciphisi kakhulu iqondo lobushushu beglasi yepolymer.
2. Ukuthambisa kwangaphandle
Ukuthambisa kwangaphandle kubhekiselele kwindlela yokuthambisa yojongano.Izithambisiukubambelela kumphezulu we-resin etyhidiweyo okanye kumphezulu womatshini wokucubungula kunye nokubumba ukwenza i-lubricant molecular layer.Ngenxa yobukho be-lubricant molecular layers, i-interface ye-lubrication yenziwa, enciphisa ukungqubuzana phakathi kwe-resin kunye nomatshini wokucubungula.I-viscosity yefilimu ye-lubrication interface kunye nokusebenza kwayo kakuhle kwe-lubrication kuxhomekeke kwindawo yokunyibilika kunye nobushushu bokusebenza kwe-lubricant.Ngokubanzi, izithambiso ezinamatsheyini ekhabhoni amade emolekyuli zineziphumo ezingcono zokuthambisa ngenxa yokukwazi ukugcina imiphezulu emibini yokukhuhlana kude.

3. Kwenzeka ntoni ukuba i-lubricant yePVC ayisetyenziswanga kakuhle?
Ibinzana elithi 'idosi encinci, isiphumo esihle' sichaza izithambiso zePVC.Indima yezithambiso ze-PVC kwi-PVC processing ayikho ngaphantsi kwe-stabilizers.Ukusetyenziswa kwayo ngokubanzi kulandela imigaqo engqongqo, efana nebhalansi yokutyibilika yangaphakathi nangaphandle, idosi ephakathi, njl.njl. Ukuba akukho kugxininiswa okwaneleyo kwii-lubricants ze-PVC kwaye ziyaphambuka kwimigaqo ekufuneka ilandelwe xa isetyenziswa, iya kuba yintoni impembelelo ukuba i-PVC lubricants azisetyenziswanga kakuhle?
(1) Ukuthanjiswa okungalungelelananga kwangaphakathi nangaphandle
I-sliding yangaphandle egqithisileyo, nangona isantya se-extrusion sikhawuleza, izinto eziphathekayo ziyakwazi ukukhula kwaye iplastiki ayilungile;Ukutyibilika okugqithileyo kwangaphakathi, umthamo omkhulu we-extrusion, kunye neplastiki yempahla engalunganga.Ukuthanjiswa okulambathayo kokuqala kunokubangela itorque engaphezulu ye-extrusion.Ukuthambisa okungonelanga kwinqanaba lamva kunokukhokelela kwi-lubrication eyaneleyo kwicandelo le-homogenization, icandelo loxinzelelo, kunye necandelo lokufa le-screw, okubangela ukuchetywa kwezinto ezinzima kunye nokuchaphazela umgangatho womphezulu kunye nokusebenza kwangaphakathi kwemveliso ekhutshweyo.Kwiimeko ezinzima, kunokubangela ukubola.

(2) Ubuninzi obugqithisileyo be-lubricant esetyenzisiweyo
Izithambiso azikho ngcono xa kukho izixa ezikhulu.Ngenxa yokungahambelani phakathi kwee-lubricants kunye ne-PVC resin, ukongezwa ngokugqithiseleyo kwezinto zokuthambisa kunokuba nemiphumo emibi kwinkqubo yokudibanisa i-PVC.Ibhalansi yangaphakathi nangaphandle ye-lubrication ekhankanyiweyo ingaphakathi komda othile, njengoko inkqubo yokudibanisa i-lubricant kunye ne-polyvinyl chloride inemiphumo emibi.Kwimveliso yokwenyani, iingxaki ezininzi zokusetyenzwa kunye nemiba enxulumene nokuzinza kwe-thermal, kunye neziphene ezininzi kwiimveliso, zinokubangelwa kusetyenziso olugqithisileyo lwe-lubricant.
