Polyethylene wax, ekwabizwa ngokuba yi-polymer wax, isetyenziswa kakhulu ngenxa yokumelana nokubanda okugqwesileyo, ukumelana nobushushu, ukumelana neekhemikhali, kunye nokumelana nokunxiba.Kwimveliso eqhelekileyo, le wax inokongezwa ngokuthe ngqo kwi-polyolefin processing njenge-additive, enokuthi inyuse i-luster kunye nokusebenza kwemveliso.Njenge-lubricant, ineekhemikhali ezizinzileyo kunye neempawu ezilungileyo zombane.Xa kuthelekiswa nePVC kunye nezinye izinto zokuthambisa zangaphandle, i-polyethylene wax inefuthe elinamandla lokuthambisa langaphakathi.
Fischer Tropsch waxubukhulu becala yenziwe nge-linear, i-alkanes ye-carbon ephezulu egcweleyo kunye nobunzima bemolekyuli phakathi kwe-500 kunye ne-1000, enika le khemikhali ngesakhiwo esihle sekristale, indawo ephezulu yokunyibilika, uluhlu oluncinci lokunyibilika, umxholo we-oyile ophantsi, ukungena okuphantsi, ukuhamba okuphantsi, ukunyibilika okuphantsi. i-viscosity, ubunzima, ukumelana nokunxiba, kunye nokuzinza okuphezulu.
Umahluko obalulekileyo phakathi kweFischer Tropsch wax eyenziwe ngewax kunye nepolyethylene ngokubanzi kukuba:
(1) Ubunzima bemolekyuli.Ubunzima be-molecular of Fischer Tropsch wax buphantsi kakhulu kune-PE wax, kunye neentambo ezincinci ze-branched kunye ne-crystallinity ephezulu.Kulula ukungena kumakhonkco aphezulu e-viscosity macromolecular, ukunciphisa kakhulu ukunyibilika kwe-viscosity.Inomfuduko ophantsi ngexesha lokucubungula kunye nefuthe elicacileyo lokuthambisa kwinqanaba lamva.
(2) I-Fischer Tropsch wax yi-alkane edibeneyo egcweleyo edibeneyo engaqulathanga i-double bonds, inamandla okulwa ne-antioxidant, kwaye imveliso inokumelana nemozulu elungileyo.
(3) I-viscosity ye-wax ye-Fischer Tropsch iphantsi kakhulu kune-PE wax.Kuphela malunga ne-10. Imali encinci inokufezekisa umphumo ofanayo wokuthambisa.Ukusetyenziswa kuphela kwe-70-80% ye-PE wax.I-wax ye-Fischer Tropsch inokuhambelana kakuhle kunye ne-PVC kwaye ingasetyenziselwa njengezinto zokuthambisa zangaphakathi nangaphandle.Ingasetyenziselwa njenge-lubricant yangaphakathi elungileyo ukulawula ngokufanelekileyo iimeko zokucheba, ukukhuthaza ukuhamba, ukulawula ukukhuhla kunye neempawu zokunyibilika, ngaloo ndlela kuphuculwe ukuzinza kwe-thermal.Kwangaxeshanye, ngenxa yobukristale obuphezulu kunye nesakhiwo somgca ophezulu, iFischer Tropsch wax yenza ukuba iimveliso zePVC zifezekise ezona zakhiwo zibalaseleyo zomzimba kunye nokusebenza.Ngokweemfuno, inkqubo ye-Fischer Tropsch inokudibanisa i-alkanes kunye nobude obuhlukeneyo bekhonkco ukutshintsha ubunzima be-molecular yemveliso yokugqibela kwaye yenze uluhlu lweemveliso.
Eyona ndlela iphambili yokwenza izinto zokuthambisa zangaphandle
Ngokwesiqhelo, i-lubricant yangaphandle ye-PVC yindawo ephezulu yokunyibilika ene-wax engekho polarity okanye i-polarity ephantsi, indawo yokunyibilika ephezulu ye-50-200 ℃, kunye nobunzima obukhulu bemolekyuli.
Indlela yokusebenza kukusebenzisa ukungahambelani kwayo ukwenza umaleko wokuthambisa ngaphandle kwendawo yePVC yokunyibilika okanye iyunithi yokuqukuqela, ukuphucula ukungqubana phakathi kwemibuso yeeyunithi zokuhamba kunye naphakathi kokunyibilika kunye nomgangatho wesinyithi.Kulula ukugawula kumaqondo obushushu aphezulu, kodwa akulula ukugawula kwiqondo lobushushu begumbi.
Impembelelo yezithambiso kwiimveliso
Isithambiso sangaphandle, ukwenza iplastiki ukusuka ngokukhawuleza ukuya kucotha, ukusebenza kwemveliso ukusuka phezulu ukuya ezantsi, kunye nokuhamba ukusuka kokubi ukuya kokulungileyo ukuya kokuphazamiseka.
Kwinqanaba lokuqala lokulungiswa kwe-extrusion, xa iinqununu ze-resin zihambisa i-friction kunye nomnye, indawo yokunyibilika ye-lubrication yangaphandle iphezulu kwaye akukho ukunyibilika, okungayi kulibazisa iplastiki.Kwinqanaba eliphakathi kunye nasemva kokucutshungulwa, ubushushu bokunyibilika buyanda, kwaye i-lubricant yangaphandle enyibilikisiweyo igubungela phakathi kwezinyibiliko, ngokufanelekileyo ukulibazisa iplastiki kunye nokuphucula ukunamathela ngesinyithi, ukuthintela ukunyibilika okugqithisileyo kokunyibilika kunye nokubonelela ngokusebenza kakuhle kokudiliza.
