Abrasives-ka tayada sare leh waa in laga sameeyaa qolof hickory oo tayo sare leh sida alaab cayriin ah, kuwaas oo la jajabiyey, la safeeyey, la camiray oo la dhaqay, lagu daaweeyay daroogo oo lagu farsameeyo iyada oo loo marayo baaritaanno badan. Abrasive qolof walnut ma aha oo kaliya xidhashada adkaysi iyo cadaadis u adkaysta, laakiin sidoo kale kuma milmi biyo acidic iyo alkaline, oo leh awood wasakh xoog leh iyo xawaaraha sifaynta degdeg ah. Abrasives qolof Walnut in ka dib markii hab gaar ah (si meesha looga saaro ay midabka, baruurta, dufan, korontada lacag nadiif ah ion nadiif ah), si ay qolof midhaha abrasives ee daaweynta biyaha leeyahay waxqabadka saarista saliid xoog leh, marka lagu daro qaybaha adag, fududahay in dib loo dhaqo iyo waxqabadka kale ee aad u fiican, waxaa loo isticmaali karaa in oilfield daaweynta bulaacada saliidda ah. Haddaba waa maxay sifooyinka iyo isticmaalka tayada sare leh ee qolof walnut?
qolof walnut ahwaa jiil cusub oo xoqan si loo beddelo quartz ciid carrasive, hagaajinta tayada biyaha iyo si weyn u yareeyaan kharashka daaweynta biyaha. Waxay leedahay iska caabin xooggan oo cadaadis ah. Marka loo eego xogta laga helay tijaabooyinka la xidhiidha, celceliska xadka cadaadiska ee miraha qolofka walnut ee leh cabbirka walxaha 1.2-1.6mm waa 0.2295KN (23.40kgf). Celceliska xadka cadaadisku wuxuu ahaa 0.165KN (16.84kgf) ee miraha qolofka walnut ee dhexroorka 0.8-1.0mm. Isla mar ahaantaana, sifooyinka kiimikaad ee qashinka walnut waa mid aad u deggan oo aan ku jirin walxaha sunta ah, milanka acid, alkali iyo biyaha waa mid aad u yar, luminta qolofka walnut ee xalka hydrochloric acid waa 4.99% iyo xal sodium hydroxide waa 3.8%, taas oo aan sababin hoos u dhaca tayada biyaha.
qolof walnut ahisticmaala:
Dhinaca kale, qolof walnut sida warbaahinta shaandhaysa ayaa awood u leh warbaahinta shaandhada caadiga ah si ay u sii haysato walxaha laalla ee biyaha wasakhda ah; dhanka kale, warbaahinta filter qolof walnut waxay ku tiirsanaan kartaa sifooyinkeeda gaarka ah ee physicochemical si ay meesha uga saarto walxaha saliidda emulsified ee biyaha wasakhda ah ee soo kabashada saliidda adoo ku dhajinaya dusha sare ee warbaahinta shaandhada ama isku-dhafka dusha sare ee warbaahinta shaandhada.
Isticmaalka qolofka walnut sida adsorbent ayaa si cilmiyeysan loo xaqiijiyay. Si kastaba ha noqotee, viscosity iyo xiisadda dusha sare ee saliidda saliidda ayaa si rogaal celis ah u saameeya heerka adsorption ee qolofka walnut, ka soo kabashada saliidda qolofka walnut aad ayey uga badan tahay warbaahinta kale ee aqueous, waxaana lagu gaari karaa cadaadis xoog leh oo keliya. Isla mar ahaantaana, warbaahinta shaandhada qolofka walnut waxay ku habboon tahay sifaynta biyaha wasakhda ah ee si fiican loo dhaqo ka dib daaweynta ka hor.
