Qalabka sibidhka ku salaysan ayaa si weyn loogu isticmaalaa dhismaha, waddooyinka, buundooyinka, tunnelyada iyo mashaariicda kale. Sababtoo ah alaabta ceeriin ee badan, qiimaha jaban iyo dhismaha habboon, waxay noqdeen qalab dhisme oo muhiim ah. Si kastaba ha ahaatee, walxaha sibidhka ku salaysan ayaa sidoo kale la kulma dhibaatooyinka qaar ee codsiyada la taaban karo, sida iska caabbinta dildilaaca hooseeya, caabbinta biyaha liidata iyo shuruudaha sare ee dareeraha koollada sibidhka inta lagu jiro dhismaha. Si loo xalliyo dhibaatooyinkan, cilmi-baarayaashu waxay isku dayeen inay ku daraan walxaha polymer-ka ee kala duwan walxaha sibidhka ku salaysan si kor loogu qaado waxqabadkooda.Hydroxypropyl methylcellulose (HPMC), Sida caadiga ah loo isticmaalo walxaha polymer-ka ee biyaha lagu milmo, ayaa si ballaaran loo isticmaalay si loo hagaajiyo sifooyinka kala duwan ee alaabta cement-ku salaysan sababtoo ah sifooyinka wanaagsan ee rheological, saamaynta dhumucdiisuna, haynta biyaha iyo caabbinta biyaha.
1. Tilmaamaha aasaasiga ah ee hydroxypropyl methylcellulose
KimaCell®Hydroxypropyl methylcellulose waa iskudhis polymer ah oo lagu helay wax ka beddelka kiimikaad ee cellulose dabiiciga ah, oo leh milmayn biyo wanaagsan, dhumuc, xajin biyaha iyo xasilloonida sare. Waxay hagaajin kartaa viscosity, dareeraha iyo ka-hortagga kala-soocidda walxaha sibidhka ku salaysan, iyo sidoo kale waxay leedahay hawo-mareenka qaarkood, ka-hortagga wasakhowga iyo sifooyinka gabowga. HPMC waxaa caadi ahaan loo isticmaalaa agabka dhismaha sida hoobiye, shabiimaadka, hoobiye engegan, iyo dahaarka, oo waxay ka ciyaartaa door muhiim ah hagaajinta sifooyinka rheological ee alaabta sibidhka ku salaysan.
2. Hagaajinta sifooyinka rheological ee walxaha sibidhka ku salaysan ee hydroxypropyl methylcellulose
Tilmaamaha rheological ee walxaha ku salaysan sibidhka ayaa muhiim u ah waxqabadka dhismaha, gaar ahaan habka bamgareynta, dhismaha, iyo dahaarka dusha sare. Guryaha rheological ee wanaagsan waxay hagaajin karaan waxtarka dhismaha waxayna hubin karaan tayada dhismaha. Ku darida HPMC waxay si wax ku ool ah u wanaajin kartaa dareeraha walxaha sibidhka ku salaysan. Gaar ahaan, HPMC waxay kordhisaa viscosity ee koollada sibidhka, taas oo ka dhigaysa isku dhafka mid deggan oo yareynaya dhacdooyinka kala soocida. Marka la eego xaaladaha saamiga biyaha-sibidhka ee hooseeya, HPMC waxay si wax ku ool ah u wanaajin kartaa shaqada shubka iyo hoobiye, taasoo ka dhigaysa inay yeeshaan dareere wanaagsan, iyadoo sidoo kale yareyneysa heerka uumiga alaabta iyo sii dheereynta waqtiga dhismaha.
3. Hagaajinta iska caabinta dildilaaca ee alaabta sibidhka ku salaysan ee HPMC
Maaddooyinka sibidhka ku salaysan waxay u nugul yihiin dildilaaca inta lagu jiro habka adkeyn, inta badan waxaa sabab u ah arrimo ay ka mid yihiin qalajinta qalajinta, isbeddelka heerkulka, iyo culeysyada dibadda. Ku darida HPMC waxay si wax ku ool ah u wanaajin kartaa iska caabbinta dildilaaca ee alaabta sibidhka ku salaysan. Tani waxay inta badan sabab u tahay haynta wanaagsan ee biyaha iyo saamaynta dhumucda ee HPMC. Marka HPMC lagu daro walxaha sibidhka ku salaysan, waxay si wax ku ool ah u yaraynaysaa uumiga biyaha waxayna hoos u dhigtaa xawliga adkaanta koollada sibidhka, taas oo hoos u dhigaysa dildilaaca yaraanshaha ee ay keento isbedbeddelka xad dhaafka ah ee biyaha. Intaa waxaa dheer, HPMC waxay sidoo kale wanaajin kartaa qaabdhismeedka gudaha ee alaabta cement-ku-saleysan, waxay kordhisaa adkaantooda iyo iska caabbinta dildilaaca.
4. Hagaajinta caabbinta biyaha iyo adkeysiga walxaha sibidhka ku salaysan
Iska caabbinta biyaha iyo adkeysiga walxaha ku salaysan sibidhka ayaa ah mid ka mid ah tilmaamayaasha muhiimka ah ee codsigooda mashaariicda dhismaha. Sida polymer-ka molecular sare, HPMC waxay wanaajin kartaa iska caabbinta biyaha ee alaabta sibidhka ku salaysan. Unugyada HPMC waxay leeyihiin dheecaan xoog leh waxayna samayn karaan lakab fuuqbax deggan oo koollada sibidhka ah si loo yareeyo gelitaanka biyaha. Isla mar ahaantaana,KimaCell®HPMC waxay sidoo kale wanaajin kartaa qaab-dhismeedka yar-yar ee alaabta cement-ku-salaysan, waxay yaraynaysaa porosity-ga, oo sidaas awgeed wanaajiso ka-hortagga walxaha iyo caabbinta biyaha. Deegaannada gaarka ah qaarkood, sida deegaanka qoyan ama xidhiidhka muddada-dheer ee biyaha, isticmaalka HPMC waxa ay si weyn u wanaajin kartaa adkaysiga walxaha sibidhka ku salaysan.
5. Saamaynta dhumucda HPMC ee alaabta sibidhka ku salaysan
Saamaynta dhumucda ee HPMC ee alaabta sibidhka ku salaysan waa mid ka mid ah qodobbada muhiimka ah ee codsigeeda ballaaran. Xabagta sibidhka, HPMC waxay samayn kartaa qaab-dhismeedka shabakad saddex-cabbir ah iyada oo loo marayo isbeddelka qaab-dhismeedkeeda kelli, taas oo si weyn u kordhinaysa viscosity ee koollada. Saamayntan dhumucdeedu maaha oo kaliya inay ka dhigi karto walxaha sibidhka ku salaysan si aad u xasilan inta lagu jiro dhismaha iyo ka fogaanshaha kala-soocidda koollada sibidhka, laakiin sidoo kale waxay hagaajinaysaa saameynta daahan ee dhejiska iyo jilicsanaanta dusha dhismaha ilaa xad. Hoobiyaha iyo walxaha kale ee sibidhka ku salaysan, saamaynta dhumucda ee HPMC waxay si wax ku ool ah u wanaajin kartaa ku shaqaynta iyo la qabsiga alaabta.
