I-HPMC, ekwabizwa ngokuba yi-hydroxypropylmethylcellulose, i-polymer 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 umthamo wamanzi 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 nokubambelela, 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.
