I-HPMC, ekwabizwa ngokuba yi-hydroxypropylmethylcellulose, yipolymer esebenzayo ethe yafumana ukwamkelwa ngokubanzi kwizicelo ezahlukeneyo zemizi-mveliso.Ngumgubo omhlophe ongenavumba, ongenancasa, onyibilika lula emanzini nakwezinye izinyibilikisi eziphilayo.I-HPMC yenziwe ngokuguqula iikhemikhali zeselulosi yendalo ephuma kwixolo lomthi.Esona sicelo sixhaphakileyo se-HPMC sikwishishini lokwakha, apho lisetyenziswa njengesona sithako siphambili sokunamathelisa iithayile ezisekelwe kwisamente.
I-adhesives tile esekelwe kwi-cement isetyenziswa ngokuqhelekileyo ekwakhiweni kwezakhiwo zokuhlala kunye nezorhwebo.Zikhethwa ngaphezu kweendonga zesamente zesintu ngenxa yokuqina kwazo okuphezulu kwebhondi, ukuqina okukhulu kunye namaxesha omisa ngokukhawuleza.Ukongeza i-HPMC kwi-adhesive tile esekelwe kwisamente kunokuphucula iimpawu zayo ze-rheological kunye nokuphucula ukusebenza kwayo.Ikwaphucula ukusetyenzwa kwaye inceda ukunciphisa ukugcinwa kwamanzi.
Indima ye-HPMC kwi-adhesive tile ye-cementitious ayinakugxininiswa.Ineenzuzo ezininzi, kuquka:
1. Ukuphucula ukugcinwa kwamanzi: I-HPMC ineempawu ezibalaseleyo zokugcina amanzi, oku kuthetha ukuba inokugcina ngokufanelekileyo ubungakanani bamanzi afunekayo kwi-adhesive.Oku kwenza i-adhesive ibe bhetyebhetye ngakumbi kwaye iphucula ukuqhubekeka kwayo.
2. Ukuphucula ukutyeba: I-HPMC isebenza njenge-agent yokuqina kwii-adhesives zetayile esekwe kwisamente.Iphucula i-viscosity ye-adhesive, ivumela ukuba isetyenziswe ngokulula kwiindawo ezinkulu ngaphandle kokuvuza okanye ukuqhuba.
3. Ukuphucula amandla okudibanisa: I-HPMC iphucula amandla okudibanisa phakathi kwe-adhesive kunye ne-substrate.Oku kubangelwa ukukwazi kwayo ukunciphisa ukubunjwa kweengxowa zomoya, ezinciphisa ibhondi.
4. Ukuphucula ukumelana nokuqhekeka: I-HPMC ibonelela nge-elasticity eyandisiweyo kwi-adhesive.Oku kunceda ukunciphisa ukubunjwa kweentanda, ezinokuthi zibe buthathaka izibophelelo kunye nokunciphisa amandla onke esakhiwo.
5. Ukuphucula ukuqina: I-HPMC iphucula ngokufanelekileyo ukuqina kwe-cement-based tile adhesive.Kungenxa yokuba iyamelana namanzi, iikhemikhali, kunye namaqondo obushushu aphezulu, nto leyo eyenza ukuba ilungele ukusetyenziswa kwiindawo ezirhabaxa.
6. Ukuphucula ukusebenza: Ukongeza i-HPMC kwi-adhesive tile esekelwe kwi-samente kunokuphucula kakhulu ukusebenza.Ivumela i-adhesive ukuba isasazeke ngokutyibilikayo phezu komhlaba ukuze kugqitywe ngakumbi, okuhambelanayo.
7. Uphuculo lwe-Consistency: I-HPMC iphucula ukuhambelana kunye nokunamathela, okwenza kube yinto efanelekileyo kuluhlu olubanzi lwezicelo.
Isishwankathelo, i-HPMC sisithako esibalulekileyo ekwenziweni kwezinto zokuncamathelisa iithayile ezisekelwe kwisamente.Iimpawu zayo eziyingqayizivele ziphucula kakhulu umgangatho wokubambelela, okwenza ukuba ulungele ukwakhiwa kwezicelo ezahlukeneyo.Kuxhomekeka kwisicelo, i-HPMC ifumaneka kumabakala ahlukeneyo kunye nokwakheka.Kucetyiswa kakhulu ukuba ukhethe umthengisi othembekileyo onokubonelela ngeemveliso ezikumgangatho ophezulu zeHPMC ezihlangabezana neemfuno zakho ezithile.Ngemveliso echanekileyo kunye nobuchule bokusebenzisa obufanelekileyo, unokonwabela izibonelelo ezininzi ze-HPMC kwiiprojekthi zakho zokwakha.
