Sida loo xoojiyo iska caabbinta xoqidda balaastikada ah iyo iska caabbinta xirashada

Dooro resin-ka aasaasiga ah ee saxda ah

Badanaa polyethylene-ka miisaanka molecular-ka aadka u sarreeya (PE-UHWM) waa mid ka mid ah balaastikada ugu adkeysiga badan, doorashada PE-U·HWM waxay si fudud u hagaajin kartaa iska caabbinta xirashada agabka. Intaa waxaa dheer, balaastikada leh crystallization sare, joogto sare ayaa ka adkeysi badan xirashada adkeysiga sare. Wax ka beddelka polypropylene (PP), # Mashiinka pelletizing pp Polyolefin elastomer (POE), ethylene propylene terene rubber (EPDM), thermoplastic dynamic vulcanized rubber (TPV) (sida dynamic vulcanized PP/EPDM) ayaa badanaa loo isticmaalaa in lagu adkeeyo PP, ku darista elastomers-kuna guud ahaan waxay keentaa hoos u dhac ku yimaada iska caabinta xoqidda, sidaa darteed aad ayey muhiim u tahay in la doorto elastomer-ka ku habboon. Habka iska caabinta xoqidda waa sidan soo socota: TPV > EPDM > POE. # mashiinka sameynta granules-ka.

Isticmaal buuxiye fiican oo iska caabiya xirashada

(1) Molybdenum disulfide

Molybdenum disulfide, oo ah walxo u adkaysta xirashada, ayaa inta badan loo isticmaalaa balaastikada nayloonka. Molybdenum disulfide wuxuu u shaqeeyaa sidii wakiil crystallizing ah si loo kordhiyo crystallinity-ga nayloonka, sidaa darteed maaddada nayloonku waxay soo saartaa dusha adag oo u adkaysta xirashada. Molybdenum disulfide waxay leedahay xiriir sare oo u dhexeeya birta, marka lagu nuugo dusha sare ee birta, molybdenum disulfide molecules waxay buuxin doonaan dusha sare ee birta daloolo yar yar, waxayna ka dhigi doonaan dusha sare ee birta mid siman, taasoo ka dhigaysa molybdenum disulfide mid ku habboon xirashada xirashada ee dhacdooyinka isku dhaca nayloonka iyo birta.

(2) Garaafit

Qaab-dhismeedka graphite waa qaab-dhismeedka kiristaalka ah ee graphite macdanta, lakabka lix-geesoodka ah, qaab-dhismeedkan kiimikada ee gaarka ah wuxuu ka dhigayaa molecules-ka graphite si fudud midba midka kale marka la mariyo is-xoqid yar, iska caabbinta xirashadani si gaar ah ayey muhiim ugu tahay deegaanka iyadoo la adeegsanayo biyaha, sidaa darteed graphite waa wax lagu daro xirashada oo ku habboon oo loo isticmaalo qaybo badan oo lagu meeleeyo biyaha, sida qolofka biyaha, daabka iyo shaabadda. # Mashiinka looxa dhismaha ee pp # Mashiinka sameynta xaashida xumbo leh ee xpe

(3) Fiberglass

Faybarka galaaska wuxuu samayn karaa xiriir farsamo oo xooggan oo u dhexeeya polymers-ka, sidaa darteed faybarka galaaska wuxuu hagaajin karaa hufnaanta qaab-dhismeedka thermoplastic-ka wuxuuna hagaajin karaa iska caabbinta xirashada. Faybarka galaaska wuxuu bixiyaa xoojin wuxuuna hagaajin karaa isku-xidhka kulaylka iyo isbeddelka kulaylka ee balaastikada, isagoo si weyn u hagaajinaya iska caabbinta culeyska iyo iska caabbinta xirashada ee balaastikada.

(4) Faybar kaarboon

# Mashiinka Isku-dhafka ah ee CFRTP

Sida kiiska fiber-ka galaaska, fiber-ka kaarboonku si weyn ayuu u hagaajin karaa hufnaanta qaab-dhismeedka agabka, iska caabbinta culayska iyo iska caabbinta xirashada. Si ka duwan fiber-ka galaaska, fiber-ka kaarboonku waa faybar jilicsan oo aan xoqnayn, fiber-ka kaarboonkuna ma xoqi doono dusha sare ee is-jiidjiidka birta ama birta lagu xoqo.

Ku dar waxyaabo ku habboon oo iska caabiya xirashada

(1) Polytetrafluoroethylene (PTFE)

Polytetrafluoroethylene (PTFE) waxay leedahay isku-xidhnaan aad u hooseysa oo is-xoqid ah, molecules-ka PTFE-na waxay sameeyaan filim saliidayn ah oo ku yaal dusha sare ee qaybta inta lagu jiro is-xoqid. PTFE waxay leedahay dufan wanaagsan iyo iska caabin xirasho marka la isku xoqo, waana ku-darka ugu fiican ee u adkaysta is-xoqid marka la isticmaalayo culayska sare. Codsiyadan culayska badan leh waxaa ka mid ah shaabadaha giraanta piston-ka ee hydraulic iyo dhaqayaasha riixitaanka. Waxyaabaha ku jira PTFE ee ku jira balaastikada aan qaabaysnayn guud ahaan waa 15%, balaastikada kristalinta ahna guud ahaan waa 20%.
