isicelo

Ukwakheka kwempahla eluhlaza kanye nezakhiwo zePVC ngokhuni lwepulasitiki.

Impushana yesihlahla se-PVC kanye ne-fiber yokhuni kanye nokugcwaliswa kwe-inorganic (i-calcium carbonate), i-lubricant, i-stabilizer, i-ejenti enegwebu, isilawuli esinamagwebu, i-toner nezinye izithasiselo ezihlobene (i-plasticizer, i-ejenti eqinisayo, i-coupling agent), njll.

1, i-resin yasekhayaSG-7, i-SG-7 resin fluidity ilungele ukukhihliza amagwebu, kodwa futhi nokunciphisa izindleko zohlobo oluxubile lwe-SG-5.

2. Ukugcwaliswa ngokuyisisekelo kuyimpushana yokhuni (ngokuvamile mayelana ne-80-120 mesh ye-wood powder kanye ne-poplar wood powder ngaphezulu), futhi i-calcium carbonate i-calcium carbonate ekhanyayo (800-1000-1200 mesh).

3, izinto zokugcoba ngokuvamile zisebenzisa i-stearic acid, upharafini, i-PE wax, i-calcium stearate nezinye izinhlanganisela ngokwengxenye edingekayo ukuze kwakhiwe uhlelo lokuthambisa lwepulasitiki yokhuni.I-Stearic acid, upharafini oshibhile osebenza kahle wokugcobisa, ukonakala kwawo indawo encibilikayo ephansi (ngaphezu kwama-degree angama-50), indawo encibilikayo yokuthambisa ekunikezeni i-lubricity nayo inomphumela we-plasticizer, ithonya elinjalo ukuqina kwemikhiqizo, ikhadi lomkhiqizo d kanye nezinga lokushisa elishisayo le-thermal deformation imikhiqizo ephansi kanye nezinga lokushisa, kulula ukuguquguquka futhi kulula ukuyinisa kuthinta ukukhiqizwa.Uma i-PE wax ihlanzekile ngo-100%, indawo yokuncibilika ingafinyelela ngaphezu kwama-degree angu-100 ngeke inciphise i-vica yomkhiqizo, futhi ingakha ungqimba lwefilimu eqinile yokushisa okuphezulu kwe-wax ebusweni bomkhiqizo, ukuze ukukhanya okungaphezulu umkhiqizo ugqame kakhulu.I-calcium stearate ingasheshisa i-plasticization yezinto futhi inomphumela othile wokuzinza.

I-4, i-stabilizer, esetshenziselwa ukukhiqizwa kwe-PVC ye-stabilizer compound lead salt stabilizer, i-organic tin, i-calcium zinc stabilizer, njll. I-stabilizer evame ukusetshenziswa epulasitiki yokhuni e-China iyinhlanganisela yokuhola usawoti oqinile, enezinzuzo zentengo eshibhile nokuzinza okuhle kokushisa. .Ububi bunobuthi futhi aluhambisani nemvelo.Kodwa-ke, ingxenye yesithambisi sokuthambisa sikasawoti esiqinile esiyinhlanganisela icishe ibe ngu-50%.Umphumela wokuzinza we-calcium ne-zinc heat stabilizer mubi kakhulu kunalowo we-lead stabilizer, kodwa awuhambisani nemvelo futhi awunabo ubuthi.Ukuze kuthuthukiswe ukusebenza, i-calcium ne-zinc stabilizer ngokuvamile ihlanganiswe ne-antioxidant kanye ne-wax yokushisa ephezulu, i-stearic acid, njll., eyenziwe yaba umsizi wokucubungula we-PVC osebenza kakhulu, onezinjongo eziningi futhi osebenza kahle kakhulu ngenqubo ekhethekile.Ilungele ukukhiqizwa kwemikhiqizo ye-PVC enobungani bemvelo kanye nemikhiqizo egcwele kakhulu.Kuyi-stabilizer enhle kakhulu yokushisa kanye nomsizi wokucubungula wezinkuni - imikhiqizo yepulasitiki.A:

1. Ukuthobela imiyalelo ye-EU ROHS kanye nemithetho ye-PAHS;

2. Ku-resin efanayo ngaphansi kwesisekelo sethayela eliphilayo eliqhathaniswayo kanye ne-lead stabilizer efanelekile ukwandisa inani lokugcwalisa.

3. Indawo yokuqala yokufaka uthayela ifana ne-organic tin, i-organic tin inephunga elingavamile, i-calcium ne-zinc stabilizer ayinalo iphunga elingavamile.

4. Ukusebenza kokucubungula kungcono kune-organotin kanye ne-lead salt stabilizer, ngoba kungokwensipho ye-stearic acid, i-plasticization esheshayo.

5. Ubuningi be-calcium ne-zinc stabilizer buqhathaniswa ne-PVC resin, ngakho-ke ukuhlakazeka kwayo kungcono kune-organotin kanye ne-lead stabilizer kasawoti, okwenza kube ngcono kakhulu ekuhlakazweni kwayo ku-resin;

6. Ingathuthukisa isiphetho semikhiqizo;

7. Ukuzinza okuhle kwe-thermal kanye nombala wokuqala.

8. Engeza kancane kancane kunesilinganisi esiholela intengo efanayo

5, i-ejenti ephephetha ngokuvamile isetshenziswa ne-AC efuthayo kanye ne-ejenti ephephetha emhlophe.Izinzuzo ze-AC ekhiqiza amagwebu ivolumu enkulu yezinwele, inani lincane, okubi ukuthi ukubola okungaphelele kuzohlala kuyingxenye encane emikhiqizweni, ekusetshenzisweni kwayo kuzobonakala ukungabikho okwenziwe emkhiqizweni, i-ejenti ekhihliza amagwebu ezindaweni ezingaphezulu komkhiqizo kanye nokungabikho okwenziwe. imikhiqizo ibekezelela-isimo sezulu Impahla ingasheshisa ukuguga, ikhulule inani elikhulu lokubola kokushisa, ibangele ukubola kwemikhiqizo ishintshe umbala, i-endothermic foaming agent kanye ne-ejenti egwebulayo Ukwengeza okufanele kunganciphisa ukushisa okweqile okukhishwe ukubola kwe-ejenti efuthayo ye-AC, ukuthi umbala womkhiqizo umsulwa kakhulu.

I-6, isilawuli esinegwebu ngokuvamile sikhethwa isigaba esiphindwe kabili A isilawuli se-viscosity ephezulu, isilawuli sekilasi eliphindwe kabili A (njenge-HF-100/200/80, njll.) akugcini nje ukumelana nesimo sezulu esiphakeme, kodwa futhi sinokusebenza okuhle kakhulu kwe-plasticizing, yenza ubuso bomkhiqizo. kuhlangene kakhudlwana, isicwebezelisi esingcono.Ukwengezwa kwesilawuli esinegwebu kungasheshisa ukwenziwa kwepulasitiki futhi konge ukusetshenziswa kwamandla ekushiseni okuphansi.Isilawuli esinegwebu singalungisa kangcono ukufana nokuminyana kwezimbobo zegwebu, sinciphise ngempumelelo ukuminyana kwemikhiqizo yegwebu lepulasitiki lezinkuni.Manje, ukuze kuncishiswe izindleko, abakhiqizi abaningi bepulasitiki yokhuni bakhetha ukusebenzisa izinto eziningi ezincane zamapayipi, izinto zepulasitiki ezifana nebhodi lokukhiqiza imfucuza, umugqa odlala isisekelo, njengemikhiqizo yepulasitiki yokhuni, izinto zesibili ezibuyisela emuva ngokushesha kunezintsha. impahla eningi, enamandla ancibilikayo aphansi, ukuze umkhiqizo usebenze kangcono, ungakhetha ukuncibilika kancane kwamandla okulawula igwebu (njenge-HF - 80/901) umphumela ungcono, Yebo, intengo izoba phezulu kune HF-100 uchungechunge.

I-7, ilungele umbala wokhuni lwemvelo oyimpushana ophuzi, obomvu, omnyama, we-titanium dioxide njalonjalo.Imibala ephuzi nebomvu ayizinto eziphilayo kanye nemvelo.Inzuzo ye-toner ye-inorganic ukuthi ingcono kune-organic toner ekuphikisweni kwesimo sezulu kanye nokumelana nokufuduka kanye nokushisa okuphezulu.Okubi ukuthi inani le-toner ye-inorganic likhulu, elingafaneleki imibala ekhanyayo, kodwa intengo ishibhile.I-Organic toner ngokuphambene nalokho.Ukhuni lwemvelo luvame ukusetshenziswa ngokuhlangana ne-organic and inorganic toner.I-Titanium dioxide inohlobo lwe-rutile kanye nohlobo lwe-anatase lwesibili.Uhlobo lwe-Rutile olumboza amandla nokumelana nesimo sezulu lungcono kunohlobo lwe-anatase, ngakho-ke ukhuni lwemvelo luvamise ukuba ne-rutile titanium dioxide.

8, CPE, ngokuvamile khetha 135A uhlobo, okwamanje engabizi kakhulu toughening modifier emakethe, kwalokho ezifanele kungenza imikhiqizo ngokhuni plastic nokuqina kangcono, kodwa inani imikhiqizo ethambile ngemva ngaphezulu, naka ukulungisa inani ukusetshenziswa. .

9. I-DOP kanye namafutha kabhontshisi we-epoxy avame ukusetshenziselwa i-PVC ye-ecological wood plasticizer.I-DOP inganciphisa amandla e-intermolecular we-resin ukuze kuthuthukiswe uketshezi, futhi inokugcoba okuthile okulungele ukukhiqizwa nokucutshungulwa.Kodwa kunganciphisa i-vicar yomkhiqizo.Ikhilogremu eyodwa ye-DOP inganciphisa i-vicar ngo-3 degrees.Umphumela we-plasticizing wamafutha kabhontshisi wesoya awulungile njengalowo we-DOP, kodwa unokusimama okushisayo okuthile, okuzophinde kunciphise i-vica yomkhiqizo.Ngakho-ke, ukusetshenziswa kwe-plasticizer kufanele kuqaphe kakhulu.
