Raw khoom muaj pes tsawg leeg thiab cov khoom ntawm PVC ntoo yas.
PVC ntoo hmoov thiab ntoo fiber ntau thiab inorganic filling (calcium carbonate), lubricant, stabilizer, foaming agent, foaming regulator, toner thiab lwm yam additives (plasticizer, toughening agent, coupling agent), thiab lwm yam.
1, resin domesticSG-7, SG-7 resin fluidity yog qhov zoo rau foaming, tab sis kuj txo tus nqi sib xyaw SG-5 hom.
2. Lub filling yog ib txwm ntoo hmoov (feem ntau txog 80-120 mesh ntawm ntoo hmoov thiab ntau poplar ntoo hmoov), thiab cov calcium carbonate yog ntau lub teeb calcium carbonate (800-1000-1200 mesh).
3, lubricants feem ntau siv stearic acid, paraffin, PE wax, calcium stearate thiab lwm yam kev sib xyaw ua ke raws li qhov xav tau kev faib ua feem rau cov ntoo yas lubricant system.Stearic acid, paraffin pheej yig zoo lubrication kev ua tau zoo, nws qhov tsis zoo yog qhov qis melting point (ntau tshaj 50 degrees), qis melting point ntawm lub lubricant hauv muab lubricity kuj muaj cov nyhuv ntawm plasticizer, xws li cuam tshuam lub rigidity ntawm cov khoom, khoom d card thiab thermal deformation kub cov khoom qis nrog rau qhov kub thiab txias, yooj yim rau deformation thiab yooj yim rau precipitate cuam tshuam rau kev tsim khoom.Yog hais tias PE ciab yog 100% ntshiab, lub melting point yuav ncav cuag ntau tshaj 100 degrees yuav tsis txo cov vica ntawm cov khoom, thiab muaj peev xwm tsim ib txheej ntawm ntom kub kub ciab zaj duab xis nyob rau saum npoo ntawm cov khoom, thiaj li hais tias lub brightness ntawm nto. cov khoom yog qhov tseem ceeb dua.Calcium stearate tuaj yeem ua kom cov khoom siv plasticization thiab muaj qee yam kev ruaj ntseg.
4, stabilizer, siv rau PVC ntau lawm stabilizer compound lead ntsev stabilizer, organic tin, calcium zinc stabilizer, thiab lwm yam. Lub stabilizer feem ntau siv hauv ntoo yas hauv Suav teb yog cov hmoov txhuas ntsev stabilizer, uas muaj qhov zoo ntawm tus nqi pheej yig thiab zoo thermal stability. .Qhov tsis zoo yog tshuaj lom thiab tsis zoo ib puag ncig.Txawm li cas los xij, qhov kev faib ua feem ntawm cov hmoov lead ntsev stabilizer lubricant yog li 50%.Cov nyhuv ruaj khov ntawm calcium thiab zinc kub stabilizer yog qhov phem dua li cov hmoov txhuas ntsev stabilizer, tab sis nws yog ib puag ncig tus phooj ywg thiab tsis muaj tshuaj lom.Txhawm rau txhim kho qhov kev ua tau zoo, calcium thiab zinc stabilizer feem ntau ua ke nrog cov tshuaj tua kab mob antioxidant thiab kub ciab, stearic acid, thiab lwm yam, uas yog tsim los rau hauv ntau lub luag haujlwm, ntau lub hom phiaj thiab kev ua haujlwm siab PVC ua haujlwm los ntawm cov txheej txheem tshwj xeeb.Nws yog qhov tsim nyog rau kev tsim khoom ntawm ib puag ncig tus phooj ywg PVC cov khoom thiab cov khoom ntim siab.Nws yog ib qho zoo heev thaum tshav kub kub stabilizer thiab kev pab cuam rau ntoo - yas khoom.A:
1. Ua raws li EU ROHS cov lus qhia thiab PAHS cov cai;
2. Nyob rau hauv tib resin nyob rau hauv lub premise ntawm piv cov organic tin thiab lead ntsev stabilizer tsim nyog nce tus nqi ntawm muab tub lim.
3. Thawj tinting cuab yeej zoo ib yam li cov organic tin, organic tin muaj peculiar tsw, calcium thiab zinc stabilizer tsis muaj peculiar tsw.
4. Kev ua haujlwm zoo dua li organotin thiab lead ntsev stabilizer, vim tias nws yog cov tshuaj tsw qab stearic acid, kuj ceev plasticization.
5. Qhov ceev ntawm calcium thiab zinc stabilizer yog piv rau PVC resin, yog li nws cov dispersion yog zoo dua li ntawm organotin thiab lead ntsev stabilizer, uas yog ntau conducive rau nws dispersion nyob rau hauv resin;
6. tuaj yeem txhim kho qhov chaw tiav ntawm cov khoom;
7. Zoo thermal stability thiab pib xim.
8. Ntxiv me ntsis ntau tshaj li tus nqi tib yam khoom stabilizer
5, lub tshuab tshuab feem ntau yog siv nrog AC tshuab tshuab thiab tus neeg ua haujlwm tshuab tshuab dawb.Qhov zoo ntawm AC foaming tus neeg saib xyuas yog cov plaub hau loj, tus nqi me me, qhov tsis zoo yog qhov tsis tiav decomposition yuav nyob twj ywm ib feem me me hauv cov khoom, hauv kev siv cov txheej txheem yuav pom tseeb tsis ua rau cov khoom, foaming tus neeg saib xyuas rau cov khoom nto thiab tsis tuaj. Cov khoom siv hluav taws xob tiv thaiv kev nyab xeeb tuaj yeem ua kom muaj kev laus, tso tawm ntau ntawm cov cua sov decomposition, ua rau decomposition ntawm cov khoom hloov xim, dawb yog endothermic foaming tus neeg saib xyuas thiab foaming tus neeg sawv cev tsim nyog ntxiv tuaj yeem ua rau cov cua sov tshaj tawm los ntawm decomposition ntawm AC tshuab, yog li tias cov khoom xim yog ntshiab dua.
6, foaming regulator feem ntau xaiv ob chav kawm A siab viscosity regulator, ob chav kawm A regulator (xws li HF-100/200/80, thiab lwm yam) tsis tsuas yog huab cua tsis kam yog superior, tab sis kuj muaj zoo heev plasticizing kev ua tau zoo, ua rau cov khoom nto ntau compact, zoo dua gloss.Qhov sib ntxiv ntawm foaming regulator tuaj yeem ua kom plasticization thiab txuag lub zog ntawm qhov kub thiab txias.Foaming regulator tuaj yeem kho qhov sib xws thiab qhov ntom ntom ntawm qhov ua npuas ncauj, txo qhov ntom ntawm cov khoom siv ntoo yas ua npuas ncauj.Tam sim no, txhawm rau txo cov nqi, ntau lub tuam txhab yas ntoo xaiv siv ntau cov khoom siv yeeb nkab me me, cov ntaub ntawv yas xws li cov khib nyiab ntau lawm phab ntsa, cov kab uas ua si lub hauv paus, xws li cov khoom yas ntoo, cov khoom siv thib ob plasticizing rov qab sai dua tshiab. cov khoom siv ntau heev, nrog lub zog qis qis, txhawm rau ua kom cov khoom ua tau zoo dua, tuaj yeem xaiv plasticizing qeeb yaj lub zog ntawm cov ua npuas ncauj tswj hwm (xws li HF - 80/901) cov nyhuv zoo dua, Tau kawg, tus nqi yuav siab dua. HF-100 series.
7, haum rau ecological ntoo xim hmoov daj, liab, dub, titanium dioxide thiab hais txog.Cov xim daj thiab xim liab yog inorganic thiab organic.Qhov zoo ntawm inorganic toner yog tias nws zoo dua li cov toner organic hauv huab cua tsis kam thiab tsis kam mus rau kev tsiv teb tsaws thiab kub.Qhov tsis zoo yog qhov ntau ntawm inorganic toner yog loj, uas tsis haum rau cov xim ci, tab sis tus nqi pheej yig.Organic toner ntawm qhov tsis sib xws.Ecological ntoo feem ntau yog siv ua ke nrog cov organic thiab inorganic toner.Titanium dioxide muaj rutile hom thiab anatase hom ob.Rutile hom npog lub zog thiab huab cua tsis kam yog zoo dua li hom anatase, yog li ecological ntoo feem ntau nrog rutile titanium dioxide.
8, CPE, feem ntau xaiv 135A hom, yog tam sim no tus nqi-zoo toughening modifier ntawm kev ua lag luam, qhov tsim nyog ntxiv tuaj yeem ua rau cov khoom yas ntoo nrog cov tawv tawv zoo dua, tab sis cov khoom muag muag tom qab ntau dua, ua tib zoo saib xyuas cov nqi siv. .
9. DOP thiab epoxy soybean roj feem ntau yog siv rau PVC ecological wood plasticizer.DOP tuaj yeem txo cov kev sib cuam tshuam ntawm cov resin los txhim kho fluidity, thiab muaj qee yam lubrication zoo rau kev tsim khoom thiab kev ua haujlwm.Tab sis nws tuaj yeem txo qhov vicar ntawm cov khoom.Ib kilogram ntawm DOP tuaj yeem txo qhov vicar los ntawm 3 degrees.Cov nyhuv plasticizing ntawm cov roj taum pauv tsis zoo li ntawm DOP, tab sis nws muaj qee yam thermal stability, uas tseem yuav txo cov vica ntawm cov khoom.Yog li ntawd, kev siv cov yas yas yuav tsum tau ceev faj ntau dua.
