Waa maxaySaliida WPC?
wax-ka-qabsiga WPC(sidoo kale loo yaqaanSaliida WPC, amawakiilka sii deynta ee WPC) waa saliidaha ka go'an soo-saarka iyo farsamaynta isku-dhafka alwaax-caaga ah (WPC): Hagaajinta waxqabadka socodka socodka, wanaajiso tayada muuqaalka alaabta, hubi sifooyinka jireed ee alaabta, yaraynta khilaafka u dhexeeya xeryahooda polymer iyo mishiinnada processing, la yareeyo qalabku wuu xidhan yahay, qaabaynta extrusion-kuna waa mid siman. Tayadawax lagu daro saliida ee WPCayaa saameyn weyn ku leh nolosha adeegga caaryada, foosto iyo boolal ee farsamaynta caag alwaax ah, awoodda wax soo saarka ee extruder, isticmaalka tamarta ee habka wax soo saarka, dhammayn dusha sare ee alaabta iyo waxqabadka heerkulka hooseeya ee profiles. Oo haddii lagu daro stearate ee gargaarka farsamaynta alwaax ee MAH waxay wiiqi doontaa saamaynta isku xidhka ee anhydride-ka lab ah, wakiilka isku xidhka iyo hufnaanta saliidaha waa la dhimi doonaa.
Xulashadaxal saliideedka WPCtixgelin shuruudaha soo socda:
Waxay leedahay iswaafajin wanaagsan oo leh resin heerkulka sare, waxay soo saari kartaa saameyn balaastik ah oo gaar ah, waxay yaraynaysaa tamarta isku xirnaanta ee udhaxeysa molecules in resin, daciifinta molecules
, khilaaf u dhexeeya midba midka kale, yareeyo viscosity dhalaalaysa of resin, wanaajiso socodka dhalaalaysa, kor u simbiriirixan ee qaybaha resin.
Alaabooyinka WPC waxaa ka mid ah codsiyo badan, kuwaas oo dhan waxay isticmaali doonaan saliidaha inta lagu guda jiro wax soo saarka tayada dusha sare ee sagxadaha, saqafka, codsiyada gidaarka gidaarka si loo hagaajiyo waxqabadka habaynta iyo bixinta tayada dusha sare, iwm.
Saliida WPC ee ugu fiican waa inay noqotaa mid shaqaynaysa, ujeedadu waa in la sameeyo qalabaynta si ay u ciyaaraan sifooyinka ugu fiican, kordhinta wax soo saarka, iyo horumarinta tayada alaabta:
1. Isdhexgalka molecular ee polymers/polymers
2. Dardar saamaynta plasticizing;
3. Iska yaree viscosity dhalaalka;
4. Iska yaree qulqulka iyo isticmaalka tamarta;
5, Polymer/Filler Interface interaction
6, Kor u kala firdhiso budada alwaax ama filler dabiiciga ah;
7. Wax ku darso qoynta buuxinta;
8, lubricated polymer buuxiyey iyo interface bir kulul ama la qaboojiyey;
9. Hagaajinta hantida duminaysa ee alaabta ku jirta baaldiga extrusion iyo dusha sare ee dhinta;
10. Iska yaree khilaafyada iyo xidhashada;
11. Bixinta saliidayn Gudaha & Dibadda ee alaabta WPC
Waxaa jira wax badan oo kala duwansaliidaha caagga ah ee alwaaxsidasaliid silikoon ku salaysan SILIKE Silimer 5400, ethylene bis-stearamide (EBS), stearate zinc, waxes paraffin, iyo PE oxidized. Oo maxay yihiinkala duwanaanshaha saliidaha wpc? Miisaanka molecular, qiyaasta, waxqabadyadu waa arrimo saameynaya oo kala duwan oo leh waxqabadyo kala duwan.Saliidaha ku salaysan Silikoonwaxay aad ugu adkaystaan xidhashada iyo jeexjeexa, iyo sidoo kale kulaylka iyo kiimikooyinka. Waxay sidoo kale yihiin kuwo aan sun ahayn oo aan guban karin, iyaga oo ka dhigaya doorasho ku habboon codsiyo badan. Saliidaha silikoon-ku-salaysan waxa kale oo ay yarayn karaan khilaafyada u dhexeeya qaybaha dhaqaaqa, taas oo gacan ka geysan karta kordhinta nolosha WPC-yada.
Waa maxay ku saabsan qiyaasta saliidda caagga ah ee alwaax?
Guud ahaan, isku-dhafka balaastikada alwaax (WPC) waxay isticmaalaan labanlaab ka badan saliidaha caagagga caadiga ah. Isku-darka alwaaxyada alwaaxyada leh fiber alwaax ah 50% ~ 60%, qadarka dufanka leh ee alaabta ku salaysan HDPE waa 4% ~ 5%, qadarka saliidda ee walxaha ku salaysan PP waa 1% ~ 2%, iyo qadarka dufanka leh ee PVC. maadada waa 5% ~ 10%. Si kastaba ha ahaatee, qiyaasta dhabta ah waxaa lagu hagaajin karaa iyadoo loo eegayo qaababka iyo hababka kala duwan ee shirkadaha.SILIKE silimer 5400waxay ku siin doontaa waxqabadyo wanaagsan oo leh qiyaas yar oo leh 1.5% ~ 3%.
Chengdu Silike Technology Co.,LTD waa aShiinaha WPC soo saaraha saliidahasi ay u bixiyaansaliid silikoon ku salaysan oo loogu talagalay WPC. Waxyaalaha lagu daro saliidaha ayaa si gaar ah loogu horumariyay farsamaynta iyo soosaarka PE WPC iyo PP WPC (qalabka caagagga alwaax) sida decking WPC, bowd WPC, iyo walxaha kale ee WPC, iwm. oo ay ku jiraan kooxaha firfircoon ee polar, waafaqid aad u fiican oo leh resin iyo budada alwaax, habka wax-soo-saarka iyo wax-soo-saarka ayaa hagaajin kara kala firdhinta budada alwaax, ma saameynayso saameynta is-waafajinta ee nidaamka, waxay si wax ku ool ah u hagaajin kartaa sifooyinka farsamada ee alaabta. Wakiilkan la sii daayo ee isku-dhafka WPC wuxuu bixiyaa waxqabadyo ka badan marka loo eego ethylene bis-stearamide (EBS), stearate zinc, waxes paraffin, iyo PE oksaydhized, iyo saliidahani waa mid kharash-ku-ool ah oo leh sifeyn aad u fiican, waxay hagaajin kartaa guryaha wax-soo-saarka resin matrix, laakiin sidoo kale waxay sameeyaan Alaabta si siman u sii, sii ka samaysan caag alwaax ah qaab cusub.
