Barium sulfate waa walxo ceeriin kiimiko ah oo aan organic ahayn oo muhiim ah oo laga soo shaqeeyay barite ceyriinka ah.Ma aha oo kaliya inay leedahay waxqabadka indhaha ee wanaagsan iyo xasiloonida kiimikada, laakiin sidoo kale waxay leedahay sifooyin gaar ah sida mugga, cabbirka tirada iyo saameynta isdhexgalka.Sidaa darteed, waxaa si weyn loogu isticmaalaa daahan, balaastikada, waraaqaha, caag, khad iyo midabka iyo beeraha kale.Nanometer barium sulfate waxay leedahay faa'iidooyinka aagga sare ee gaarka ah, dhaqdhaqaaqa sare, kala firdhinta wanaagsan, iwm. Waxay muujin kartaa waxqabad aad u fiican marka lagu dabaqo walxaha isku dhafan.HCMilling (Guilin Hongcheng) waa soo-saare xirfad lehbariisshiididmashiinada.Ourbariisrullaluistemadka toosanwarshad Mashiinku wuxuu shiidi karaa 80-3000 budada barite mesh.Kuwa soo socdaa waa horudhac goobaha codsiga ee nano barium sulfate.
1. Warshadaha caaga ah - ka dib markii la farsameeyo bariisshiididmashiinka
Ku darista nano barium sulfate oo lagu farsameeyay mishiinka wax shiida barite ee polymer si loo helo walxo isku dhafan oo leh xoog sare iyo adag ayaa soo jiidatay dareen badan iyo dheeraad ah.Tusaale ahaan, barium sulfate waxaa lagu dari karaa polyetylen (PE), polypropylene (PP), polylactic acid (PLA), polytetrafluoroethylene (PTFE) iyo walxo kale.Gaar ahaan, sifooyinka farsamada ee barium sulfate ayaa si weyn loo hagaajiyay ka dib markii wax laga beddelo dusha sare.
Inta badan isku-dhafka polymer-ka, iyadoo la kordhinayo qadarka wax-bedelka, xoogga iyo adkaanta walxaha isku-dhafka ah ayaa kordha marka hore ka dibna hoos u dhaca.Tani waa sababta oo ah qadarka xad-dhaafka ah ee wax-ka-beddelku wuxuu u horseedi doonaa xayeysiis-lakab badan oo muuqaal ah oo ku yaal dusha sare ee nano barium sulfate, taasoo keenaysa qallafsanaan daran ee polymer-ka, saameynaya sifooyinka farsamada ee alaabta isku dhafan, oo adkeyneysa in la ciyaaro sifooyinka ugu fiican buuxinta aan organic ahayn;Qadar yar oo wax-beddele ah ayaa kordhin doonta cilladaha is-dhexgalka ee u dhexeeya nano barium sulfate iyo polymer, taasoo keentay hoos u dhaca sifooyinka farsamada ee isku-dhafka.
Marka lagu daro qadarka kor ku xusan ee wax ka beddelka dusha sare wuxuu saameyn weyn ku leeyahay sifooyinka farsamada ee isku-dhafka, qadarka barium sulfate sidoo kale waa arrin muhiim ah.Tani waa sababta oo ah xoogga nano barium sulfate waa mid aad u weyn, kaas oo door ka ciyaari kara wax-qabadka marka lagu daro isku-dhafka, sidaas darteed soo saarista saameyn xoojin ah.Si kastaba ha noqotee, marka maadada nano barium sulfate ay aad u sarreyso (in ka badan 4%), sababtoo ah isugeynteeda isku-dhafka ah iyo ku-darka walxaha aan dabiiciga ahayn, cilladaha matrixka ayaa kordha, taas oo ka dhigaysa isku-dhafka mid aad u nugul jabka, sidaas darteed samaynta sifooyinka farsamada ee isku dhafan ayaa ka sii daran.Sidaa darteed, qadarka dheeriga ah ee barium sulfate waa in uu ahaado mid ku jira sifooyinka farsamada ee ku habboon.
2. Warshadaha dahaarka - ka dib markii la farsameeyobariisshiididmashiinka
Sida nooc ka mid ah midabaynta, barium sulfate ayaa si weyn loogu isticmaalaa daahan waxayna door muhiim ah ka ciyaartaa hagaajinta dhumucda, caabbinta abrasion, caabbinta biyaha, caabbinta kulaylka, qallafsanaanta dusha sare iyo iska caabbinta saameynta daboolka.Intaa waxaa dheer, sababtoo ah nuugista saliidda hooseeya iyo awoodda buuxinta sare, waxaa loo isticmaali karaa daboolka biyaha ku salaysan, muraayadaha, daboolka dhexdhexaadka ah iyo saliidaha saliidda leh si loo yareeyo kharashka daboolka.Waxay bedeli kartaa 10% ~ 25% titanium dioxide ee daahan biyaha ku salaysan.Natiijooyinku waxay muujinayaan in caddaanka la wanaajiyey oo awoodda qarinta aan la dhimin.
Astaamaha barium sulfate ee superfine ee dahaarka waa: 1) cabbirka walxaha aad u fiican iyo qaybinta cabbirka walxaha cidhiidhi ah;2) Waa daah-furan marka lagu kala firdhiyo xalalka resin;3) Kala firdhisanaanta wanaagsan ee alaabta saldhigga ah;4) Waxaa loo isticmaali karaa sida wakiilka kala firdhiso oo lagu daro midabka organic;5) Waxay hagaajin kartaa sifooyinka jirka.
3. Warshadaha waraaqaha - ka dib habaynta by bariisrullaluistemadka toosanwarshad mashiinka
Barium sulfate waxaa inta badan loo adeegsadaa warshadaha samaynta waraaqaha sababtoo ah degenaanshaheeda jireed iyo kiimikaad ee wanaagsan, engegnaanta dhexdhexaadka ah, cadaanka weyn, iyo nuugista fallaadhaha waxyeelada leh.
Tusaale ahaan, warqadda kaarboonku waa waxbarasho caadi ah iyo sahay xafiiseed, laakiin dusha sare waa sahlan tahay in midabaynta, sidaas darteed barium sulfate ayaa looga baahan yahay inuu yeesho qiime sare oo nuugista saliidda, taas oo hagaajin karta nuugista khad ee warqadda;Xajmiga qaybku waa mid yar oo lebis ah, kaas oo ka dhigi kara waraaqda mid siman oo sababi karta daal yar oo mashiinka.
4. Warshadaha fiber kiimiko - ka dib markii la farsameeyo bariisrullaluistemadka toosanwarshad mashiinka
Fiber Viscose, oo sidoo kale loo yaqaan "suuf macmal ah", waxay la mid tahay fiber suufka dabiiciga ah ee dabiiciga ah, sida anti-static, nuugista qoyaanka wanaagsan, midabaynta fudud, iyo farsamaynta dharka fudud.Nano barium sulfate waxay leedahay saameyn wanaagsan oo nano ah.Nano barium sulfate/cellulose-ka isku dhafka ah ee dib loo soo cusbooneysiiyay oo laga sameeyay labadaba sida alaabta ceeriin waa nooc cusub oo fiber isku dhafan, kaas oo ilaalin kara sifooyinka gaarka ah ee qayb kasta.Waxaa intaa dheer, iyada oo loo marayo "is-dhexgalka" u dhexeeya iyaga, waxay ka dhigi kartaa cilladaha hal shay oo muujinaya sifooyinka cusub ee walxaha isku dhafan.
