⑵ Phucula ukutyeba kunye ne-plasticity, kwaye uphucule ulwakhiwo; i-mortar ephuculwe yi-cellulose ether kulula ukuyakha, igcina ixesha lokwakha kwaye inciphisa iindleko zokwakha.
⑶ I-cellulose ether egcina amanzi amaninzi kakhulu, ifanelekile kwizitena ezifunxa amanzi amaninzi.
4. Isizalisi seplati
⑴Igcina amanzi kakuhle, yandisa ixesha lokuvula kwaye iphucula ukusebenza kakuhle. Inamafutha amaninzi, kulula ukuwaxuba.
⑵ Phucula ukumelana nokuncipha kunye nokumelana nokuqhekeka, uphucule umgangatho womphezulu wokugquma.
⑶ Phucula indlela umphezulu wokubopha onamathela ngayo kwaye unike ubume obuthambileyo nobuthambileyo.
5. Ithayile yokuncamathelisa
⑴Izithako zomxube ezilula ukuzomisa, azihlanganisi, zonyusa isantya sokusetyenziswa, ziphucula ukusebenza kolwakhiwo, zonge ixesha lokusebenza kwaye zinciphise iindleko zokusebenza.
⑵ Ngokwandisa ixesha lokuvula, ukusebenza kakuhle kwethayile kunokuphuculwa kwaye kubonelelwe ngesiphumo esihle sokuncamathela.
6. Izinto zomgangatho ezizilinganisayo
⑴Inika uburhabaxa kwaye ingasetyenziswa njengesongezo sokulwa nokuthungwa kwenkunkuma.
⑵Phucula ukufunxwa kwamanzi kwaye uphucule ukusebenza kakuhle kokubeka umhlaba.
⑶ Lawula ukugcinwa kwamanzi kunye nokuncitshiswa kwawo, nciphisa imifantu kunye nokuncitshiswa komhlaba.
7. Ipeyinti esekwe emanzini
⑴Thintela ukuna kwemvula eqinileyo kwaye yandise ubomi besikhongozeli semveliso. Uzinzo oluphezulu lwebhayoloji, ukuhambelana okuhle nezinye izinto.
⑵ Phucula ukutyibilika kwamanzi, unike iipropati ezilungileyo zokungatshixizi, ukungatyibiliki kunye nokuthamba, kwaye uqinisekise ukuba umphezulu ugqityiwe kakuhle.
8. Umgubo wephepha lodonga
⑴ Yinyibilike ngokukhawuleza ngaphandle kwamaqhuma, nto leyo ilungele ukuxuba.
⑵ inika amandla aphezulu okubopha.
9. Ibhodi yesamente ekhutshiweyo
⑴ Inokunamathelana okuphezulu kunye nokuthamba, kwaye iphucula ukusebenza kweemveliso ezikhutshiweyo.
⑵ Phucula amandla aluhlaza, ikhuthaza ukufuma kunye nefuthe lokunyanga, kwaye yandise isivuno.
10. Iimveliso ze-HPMC zedaka elixutyiweyo
Imveliso ye-HPMC esetyenziselwa ngokukodwa i-mortar exutyiweyo igcina amanzi ngcono kunemveliso eqhelekileyo kwi-mortar exutyiweyo, iqinisekisa ukufuma okwaneleyo kwezinto ezingezizo ze-cementitious, kwaye ithintela kakhulu ukuncipha kwamandla e-bond okubangelwa kukoma kakhulu nokuqhekeka okubangelwa kukuncipha kokomisa. I-HPMC ikwanayo nefuthe elithile lokungenisa umoya. Imveliso ye-HPMC esetyenziselwa ngokukodwa i-mortar exutyiweyo i-mortar inomlinganiselo ofanelekileyo wamaqamza omoya aqeqeshwe ngomoya, afanayo nalawo amancinci, anokuphucula amandla kunye nokuthambisa i-mortar exutyiweyo. Imveliso ye-HPMC esetyenziselwa ngokukodwa i-mortar exutyiweyo i-mortar inefuthe elithile lokulibazisa, elinokwandisa ixesha lokuvula i-mortar exutyiweyo kwaye linciphise ubunzima bokwakhiwa. I-Hydroxypropyl methylcellulose (HPMC) yi-non-ionic cellulose ether eyenziwe nge-cellulose yendalo ye-polymer ngokusebenzisa uthotho lweenkqubo zeekhemikhali. Ziyi-powder emhlophe engenavumba, engenancasa kwaye engenatyhefu evuvuka ibe yisisombululo se-colloidal esicacileyo okanye esinamafu kancinci emanzini abandayo. Ineempawu zokutyeba, zokubopha, zokusasaza, zokuhlanganisa, zokwenza ifilimu, zokuyimisa, zokufunxa, zokufaka ijeli, ezingaphezulu, zokugcina umswakama kunye nezokukhusela i-colloid. I-Hydroxypropyl methyl cellulose kunye ne-methyl cellulose zingasetyenziswa kwizixhobo zokwakha, kushishino lwepeyinti, kwi-synthetic resin, kushishino lwe-ceramic, kumayeza, ekutyeni, kwimpahla yelaphu, kwezolimo, kwiikhemikhali zemihla ngemihla nakwamanye amashishini.
