I-PVC SG-5 ukuvelisa umbhobho
I-PVC SG-5 ukuvelisa umbhobho,
PVC umbhobho imveliso ekrwada,
Kwimveliso yeetyhubhu ezinzima, i-SG-5 resin ene-polymerization degree ephantsi kufuneka ikhethwe.Okukhona iphezulu iqondo lepolymerization, kokukhona ingcono iipropathi zayo zomzimba kunye noomatshini kunye nokumelana nobushushu, kodwa ulwelo olulambathayo lwentlaka luzisa ubunzima obuthile ekusetyenzweni, ngoko ke i-SG-5 resin ene-viscosity ye (1.7~1.8) × 10-3Pa• s ikhethwa ngokubanzi.
Umbhobho onzima ngokubanzi usebenzisa isizinzisi sokuzinzisa, ukuzinza kwayo kwe-thermal kulungile, ilothe ye-tribasic esetyenziswa ngokuqhelekileyo, kodwa ukuthanjiswa kwayo kumbi, ngokuqhelekileyo kunye nokuthambisa okulungileyo kwelothe, isepha ye-barium.
Ukucutshungulwa kweetyhubhu ezinzima, ukhetho kunye nokusetyenziswa kwezinto zokuthambisa kubaluleke kakhulu, kungekuphela nje ukuqwalasela ukuthambisa kwangaphakathi ukunciphisa amandla e-intermolecular, ukwenzela ukuba i-viscosity enyibilikayo iyancipha ilungele ukwenza, kodwa kwakhona ukuqwalasela ukuthambisa kwangaphandle, ukuthintela ukunyibilika. kunye nokunamathela kwentsimbi eshushu, ukwenzela ukuba ubuso bemveliso bukhanye.
Isepha yesinyithi idla ngokusetyenziselwa ukuthambisa kwangaphakathi, kwaye iwax enyibilikayo esezantsi isetyenziselwa ukuthambisa kwangaphandle.
I-filler isebenzisa ikakhulu i-calcium carbonate kunye ne-barium (umgubo we-barite), i-calcium carbonate yenza ukusebenza komphezulu wombhobho okulungileyo, i-barium inokuphucula ukubunjwa, yenza umbhobho ube lula ukumila, zombini unokunciphisa iindleko, kodwa isixa sobuninzi kakhulu siya kuchaphazela ukusebenza kombhobho, umbhobho woxinzelelo kunye ne-corrosion resistant pipe kungcono ukuba ungabongezi okanye ungeze isizalisi esincinci.
iimveliso resin PVC zidla ngomgubo omhlophe, calcium carbide SG-5 uhlobo PVC resin K ixabiso 66-68, ikakhulu isetyenziselwa extrusion umbhobho, iprofayile, bar, sheet kunye nezinye iimveliso PVC nzima, iqondo polymerization malunga 1000, molecular enkulu weight.Iintlobo ngeentlobo zeemveliso ezinzima, ezithambileyo nezingafihliyo zinokwenziwa ngokongeza iplastiki efanelekileyo kwintlaka yePVC.
Izithuthi ezicocekileyo nezigqunyiweyo kufuneka zisetyenziswe ukuthintela imvula ngexesha lothutho lwemveliso.Ukugcinwa, kufuneka kugcinwe kwindawo eyomileyo, engenamoya.
