1. Intshayelelo
Izinto zokwakha zeMichiza luhlobo lwesine olutsha lwezixhobo zokwakha zangoku emva kwentsimbi, umthi kunye nesamente, ngokukodwa kubandakanywa imibhobho yeplastiki, iingcango zeplastiki kunye neefestile, izinto zokwakha ezingenamanzi, izinto zokuhombisa, njl njl. Eyona nto iphambili i-polyvinyl chloride (PVC).
I-PVC isetyenziswa kakhulu njengezinto zokwakha kunye neeprofayili zayo zeplastiki zisetyenziswa ngokubanzi kwiingcango zangaphakathi nangaphandle kunye neefestile zezakhiwo kunye noshishino lokuhombisa, kunye neempawu ezibalaseleyo ezifana nokugcinwa kobushushu, ukutywinwa, ukonga amandla, ukugquma isandi kunye neendleko eziphakathi, njl. isingeniso, imveliso iye yaphuhliswa ngokukhawuleza.
Nangona kunjalo, iiprofayili zePVC zikwanazo ezinye izinto ezingeloncedo, ezinje ngobushushu obuphantsi, amandla empembelelo ephantsi, kunye nobunzima bokuqhuba.Ke ngoko, iipropathi zempembelelo kunye neepropathi zePVC kufuneka ziphuculwe.Ukongeza izilungisi kwi-PVC kunokuphucula ngokufanelekileyo ukuqina kwayo, kodwa izilungisi kufuneka zibe neempawu ezilandelayo: Ubushushu obuphantsi beglasi yokutshintsha;ngokuyinxenye iyahambelana PVC resin;ihambelana ne-viscosity yePVC;akukho mpembelelo ibalulekileyo kwizinto ezibonakalayo kunye nezomatshini zePVC;iimpawu ezintle zemozulu kunye nokwandiswa kokukhululwa kwesikhunta.
I-PVC esetyenziswa ngokuxhaphakileyo iziguquli zempembelelo yi-chlorinated polyethylene (CPE), i-polyacrylates (ACR), i-methyl methacrylate-butadiene-styrene terpolymer (MBS), i-acrylonitrile-butadiene-styrene copolymer (ABS), i-ethylene i-vinyl acetate copolymer (EVA) (EPR), njl.
Inkampani yethu iphuhlise kwaye yavelisa isiseko seqokobhe lePVC isilungisi JCS-817.Esi silungisi sinesiphumo esihle ekuphuculeni iplastiki kunye namandla empembelelo yePVC.
2 Umthamo ocetyiswayo
Ubungakanani be-modifier ye-JCS-817 yi-6% kwi-100 ubunzima beengxenye ze-PVC resin.
I-3 yokuvavanya ukulinganisa ukusebenza phakathi kwezilungisi ezahlukeneyo kunye nesi silungisi JCS-817
1. Lungiselela imathiriyeli yovavanyo lwePVC ngokwefomula ekwiThebhile yoku-1
Uluhlu loku-1
| Igama | Amacandelo ngobunzima |
| 4201 | 7 |
| 660 | 2 |
| PV218 | 3 |
| I-AC-6A | 3 |
| I-Titanium Dioxide | 40 |
| I-PVC (S-1000) | 1000 |
| I-Organic Tin Stabilizer | 20 |
| Calcium carbonate | 50 |
2. Uvavanyo lokuthelekisa amandla empembelelo: Hlanganisa iifomyula ezingentla kwaye udibanise i-compound kunye ne-6% yobunzima bePVC kunye ne-PVC modifiers ezahlukeneyo.
Iimpawu zomatshini zilinganiswe yi-double-roller open mill, i-flat vulcanizer, isampuli yokwenza, kunye nomatshini wokuvavanya jikelele kunye nomhloli wempembelelo elula njengoko kuboniswe kwiThebhile 2.
Itheyibhile 2
| Into | Indlela yokuvavanya | Iimeko zovavanyo | Iyunithi | Izalathisi zobugcisa (JCS-817 6phr) | Izalathisi zobugcisa (CPE 6phr) | Izalathisi zobugcisa (Isampulu yokuthelekisa i-ACR 6phr) |
| Impembelelo (23℃) | GB/T 1043 | 1A | KJ/mm2 | 9.6 | 8.4 | 9.0 |
| Impembelelo (-20℃) | GB/T 1043 | 1A | KJ/mm2 | 3.4 | 3.0 | Akukho nanye |
Ukususela kwidatha kwiThebhile 2, kunokugqitywa ukuba amandla empembelelo ye-JCS-817 kwi-PVC ingcono kune-CPE kunye ne-ACR.
3. Ukuthelekisa uvavanyo lweempawu ze-rheological: Dibanisa ukwakheka okungentla kwaye ungeze i-3% yobunzima bePVC kwikhompawundi kunye nezilungisi zePVC ezahlukeneyo uze udibanise.
Iipropati zeplastiki ezilinganiswe yiHarper rheometer ziboniswe kwiThebhile 3.
Itheyibhile 3
| Hayi. | Ixesha lePlasitiki (S) | Itorque elungelelanisiweyo (M[Nm]) | Isantya sokujikeleza (rpm) | Uvavanyo lobushushu (℃) |
| I-JCS-817 | 55 | 15.2 | 40 | 185 |
| CPE | 70 | 10.3 | 40 | 185 |
| I-ACR | 80 | 19.5 | 40 | 185 |
Ukususela kwiThebhile 2, ixesha leplastiki le-JCS-817 kwi-PVC lingaphantsi kwe-CPE kunye ne-ACR, oko kukuthi, i-JCS-817 iya kubangela iimeko eziphantsi zokucubungula i-PVC.
4 Isiphelo
Amandla empembelelo kunye nepropati yeplastiki yepropathi ye-JCS-817 kwi-PVC ingcono kune-CPE kunye ne-ACR emva kokuqinisekiswa kovavanyo.
