Ukusetyenziswa kwe-HPMC kunye ne-HEMC kwizinto zoKwakha

I-HPMC kunye ne-HEMC ziipholima ezimbini ezibalulekileyo eziye zasetyenziswa ngokubanzi kwizinto zokwakha. Badlala indima ebalulekileyo ekuphuculeni ukusebenza kunye nomgangatho wezinto zokwakha. Kweli nqaku, siya kwazisa iipropati kunye nokusetyenziswa kwe-HPMC kunye ne-HEMC kwizinto zokwakha.

I-HPMC, ekwabizwa ngokuba yi-hydroxypropyl methylcellulose, yi-ether yeselulosi ephuma kwintlama yeplanga kunye nemicu yomqhaphu. Ngumgubo ongenavumba, ongenancasa, ongenatyhefu onyibilika emanzini. I-HPMC inokugcinwa kwamanzi okugqwesileyo, ukutyeba kunye neempawu ze-emulsifying, ezenza ukuba ibe yinto ethandwayo yokudibanisa kwizinto zokwakha.

Esinye sezona zicelo zixhaphakileyo ze-HPMC zizincamathelisi zeethayile ezisekelwe kwisamente. I-HPMC inokuphucula amandla ebhondi kunye nokusebenza kwe-adhesive, kwaye inokuthintela iithayile ukuba zityibilike okanye ziwe ngexesha lofakelo. Ukongeza, i-HPMC inokunciphisa ukufunxwa kwamanzi kwiithayile, okubalulekileyo ekomelezeni nasekuphileni kwexesha elide lofakelo lweethayile.

I-HPMC ikwasetyenziswa ngokubanzi kwiikhompawundi zokuzilinganisa isamente. Iikhompawundi ezizilinganisa ngokwazo zisetyenziselwa ukulinganisa imigangatho yekonkrithi engalinganiyo, kwaye i-HPMC inokuphucula ukuhamba kwekhompawundi kunye neempawu zokulinganisa. I-HPMC iphinda ithintele i-self-leveling ikhompawundi ekwenzeni iintanda kunye nokuncipha, okubalulekileyo kwingqibelelo yenkqubo yomgangatho.

Olunye usetyenziso lwe-HPMC luguqulelo olusekwe kwisamente kunye nesamente. I-HPMC inokuphucula ukuncamathela kunye nokusebenza kodaka okanye istucco, kwaye inokwandisa ukusebenza kokungangeni kwamanzi. Oku kubalulekile ukukhusela imvulophu yokwakha kunye nokukhusela umonakalo womswakama.

I-HEMC, eyaziwa ngokuba yi-hydroxyethyl methylcellulose, yenye i-ether ye-cellulose esetyenziswa ngokubanzi kwizinto zokwakha. I-HEMC ifana ne-HPMC ngokwemigaqo yokusebenza kunye nezicelo, kodwa ineenzuzo ezithile ezizodwa ezenza ukuba zilungele izicelo ezithile.

Enye yeenzuzo eziphambili ze-HEMC yi-viscosity yayo ephezulu. Oku kuyenza ilungele ukusetyenziswa kwiidyasi ezishinyeneyo kunye neepeyinti ukuphucula ukuhamba kunye nomgangatho. I-HEMC isetyenziselwa ngokubanzi kwii-caulks kunye ne-sealants, ezinokuphucula ukuxhathisa kwamanzi kunye nokubambelela kweemveliso.

I-HEMC ikwasetyenziswa ngokuqhelekileyo kwizinto zokwakha ezisekelwe kwi-gypsum ezifana neekhompawundi ezidibeneyo kunye ne-stucco. I-HEMC iphucula ukusebenza kunye nokubambelela kwiikhompawundi ezidibeneyo kwaye iphinde ithintele ukuncipha kunye nokuqhekeka. Ukongezelela, i-HEMC inokuphucula ukunyanzeliswa kwamanzi kunye nokuxhatshazwa kwe-mildew of plasters, ezibalulekileyo kumgangatho womoya wangaphakathi wezakhiwo.

Ukuqukumbela, i-HPMC kunye ne-HEMC ziipolima ezimbini ezibalulekileyo ezinezicelo ezininzi kwizinto zokwakha. Badlala indima ebalulekileyo ekuphuculeni ukusebenza kunye nomgangatho wezinto zokwakha kunye nokunceda ukudala izakhiwo ezizinzileyo, ezisebenzayo kunye nezizinzileyo. Njengoko ezi zixhobo ziqhubeka ziphuhliswa kwaye zicokiswa, sinokulindela izisombululo ezintsha neziphucukileyo zokwakha kwixesha elizayo.
