Ekuqulunqweni kweprofayili, i-lubricant esetyenzisiweyo iyahluka ngenxa yeenkqubo ezahlukeneyo ezizinzileyo.Kwinkqubo yokuqinisa ityuwa ekhokelayo, i-stearic acid, i-glyceryl stearate kunye ne-polyethylene wax inokukhethwa njenge-lubricant;kwinkqubo yozinziso ye-calcium zinc engeyiyo inetyhefu kunye nenkqubo enqabileyo yomhlaba edibeneyo yokuzinzisa, i-stearic acid, i-butyl stearate, iparafini, pe wax kunye ne-calcium stearate inokukhethwa njengezinto zokuthambisa;kwifomula ye-organic tin, i-calcium stearate, iparafini, polyethylene oxidized wax inokukhethwa njengezithambiso.Iimpawu eziphambili zezithambiso eziqhelekileyo zezi zilandelayo:

(1) I-calcium stearate
Umgubo omhlophe, indawo yokunyibilikisa i-148-155 ℃, i-non-toxic, i-lubricity egqwesileyo kunye nokuqhubekeka, akukho ngcoliseko ye-sulfide, esetyenziswa kunye netyuwa ekhokelayo esisiseko kunye nesepha ekhokelayo, inokuphucula isantya sejeli, kwaye idosi ngokubanzi yi-0.1-0.4PHR.
(2) Polyethylene wax
Umgubo omhlophe, indawo yokuthambisa imalunga ne-100-117 ℃.Ngenxa yobunzima bayo obuphezulu bemolekyuli, indawo yokunyibilika ephezulu kunye nokuguquguquka okuphantsi, ikwabonisa isiphumo esicacileyo sokuthambisa kubushushu obuphezulu kunye nesantya sokucheba.Ifanelekile kwi-PVC engqongqo kunye ne-twin screw extrusion, kunye nenani eliqhelekileyo le-0.1-0.5PHR.
(3) I-wax ye-polyethylene ene-oxidized
Umgubo omhlophe okanye omthubi okanye iqhekeza, i-wax ye-polyethylene ene-oxid ayikahambelani ne-PVC, nangona iqulethe inani elincinci lamaqela e-polar, kodwa ukusebenza kakuhle kokuthambisa kuphezulu, okunokuphucula ukuthanjiswa phakathi kwepolymer kunye nesinyithi, ukuphucula ukusebenza kakuhle kwe-extrusion, ukuphucula ukusasazwa kwemibala, kwaye unike iimveliso ukubonakala kakuhle kunye nokukhazimla.Umthamo 0.1-0.5PHR.

(4) Stearic acid
Amasuntswana amhlophe okanye atyheli, indawo yokunyibilika 70-71 ℃.Iyaguquguquka kancinane kwi-90-100 ℃.Isetyenziswe njenge-lubricant yangaphandle kwi-processing ye-PVC enzima.Isixa ngokubanzi yi-0.2-0.5PHR, kwaye inefuthe lokuthintela ukulinganiswa kwe-chromatography, kodwa kulula ukutshiza iqabaka ukuba isixa sikhulu kakhulu.

(5) Iwax yeparafini
Indawo yokunyibilikisa i-57-63 ℃, ngaphandle kwamaqela e-polar, sisithambiso esiqhelekileyo sangaphandle.Ngenxa yeqondo eliphantsi lokunyibilika kwayo, ukuphuphuma komphunga ngokulula, kunye ne-viscosity ephantsi yokunyibilika, inokudlala kuphela indima yokuthambisa kuluhlu olumxinwa.Ilungele ukukhutshelwa nge-extruders enye kunye ne-twin screw, kunye ne-dosage jikelele ye-0.1-0.8PHR.Le mveliso inokungafihli kakuhle kwaye kulula ukuyijika ibe mhlophe.
Ngokwesiqhelo, kufumaniseka ukuba xa izithambisi ezimbini okanye ngaphezulu zisetyenziswa kunye, zineziphumo ezahlukileyo kunaxa zisetyenziswa zodwa.Ekuqulunqweni kwezinto zeprofayili, ezininzi zazo zixutywe.Inkqubo ehambelanayo kunye neempawu zezithambiso eziqhelekileyo zishwankathelwa ngolu hlobo lulandelayo:
(1) I-calcium stearate – iParafini (i-polyethylene wax) inkqubo yokuthambisa
Ukusetyenziswa kwe-calcium stearate yodwa kwifomula kunokukhawulezisa iplastiki, ukuphucula i-viscosity enyibilikayo, ukwandisa i-torque, kwaye ibe nefuthe elithile lokudiliza.Ukusetyenziswa kweparafini yodwa kubonisa ukulibaziseka kweplastiki, i-torque encitshisiweyo, kwaye akukho siphumo sokudiliza.Xa i-calcium stearate kunye ne-parafini wax (i-polyethylene wax) ixutywe kwinqanaba elithile, ibonisa umphumo omhle, kwaye ixabiso le-torque yezinto eziphathekayo lingancitshiswa kakhulu.Oku kungenxa yokuba iparafini ingena kwiimolekyuli ze-calcium stearate, iqinisa i-lubrication, ibonisa umphumo onamandla we-synergistic, kunye nokuphucula ukusasazeka kwe-lubricant.

(2) I-asidi ye-Stearic - IParafini (i-polyethylene wax) inkqubo yokuthambisa
Inkqubo iyafana naleyo ye-calcium stearate - iParafini (i-polyethylene wax) inkqubo, enokuphucula ukuzinza kwe-thermal ye-formula, ukunciphisa ukucutheka, ukuphucula ukumanzi, kunye nokuququzelela ukuchithwa.
(3) I-oxidized polyethylene wax - i-esters - i-calcium stearate
Xa i-polyethylene wax, i-ester kunye ne-calcium stearate zisetyenziselwa kunye, ixesha leplastiki lihlala lide ngokunyuka kwe-polyethylene wax, ngelixa xa i-wax ye-polyethylene ene-oxidized, i-wax yeparafini, i-ester kunye ne-calcium stearate isetyenziswa kunye, ixesha leplastiki liyanda kuqala kwaye emva koko yehla ngokunyuka kwe-polyethylene ene-oxidized isixa, ebonisa umphumo ocacileyo we-synergistic.
Ukuqukumbela, xa ufunda iprofayili ye-PVC, kuyimfuneko ukuqonda kuphela iimpawu kunye nemisebenzi ye-lubricant nganye, kodwa kunye nefuthe le-synergistic phakathi kwabo.Ukongeza, ifomula yeprofayili yePVC kufuneka ihlengahlengiswe kwaye itshintshwe ngokweyantlukwano kwizixhobo zokusebenza kunye nokubumba.
