IHydroxypropyl Methylcellulose (HPMC)yi-ether ye-cellulose engeyiyoni eguqulwe ngokweekhemikhali. Ngenxa yokunyibilika kwayo okugqwesileyo, iipropati zokwenza ifilimu, ukuqina kwayo, i-emulsification, kunye nokuhambelana kwayo nezinto eziphilayo, isetyenziswa kakhulu kwiinkalo ezahlukeneyo.
1. Izixhobo zokwakha
I-HPMC sisongezelelo esibalulekileyo kwishishini lokwakha, ngakumbi kwi-samente mortar, iimveliso ze-gypsum, izincamathelisi zethayile, kunye neenkqubo zokugquma zangaphandle (i-EIFS). Imisebenzi yayo ephambili ibandakanya:
Ukugcinwa kwamanzi kunye nokuqina: Kwiinkqubo zesamente kunye ne-gypsum, i-HPMC igcina umswakama ngokufanelekileyo, yandisa ixesha lokusebenza kwaye ithintele ukuqhekeka okanye ukulahleka kwamandla okubangelwa kukulahleka kwamanzi ngokukhawuleza.
Ukuphucula ukusebenza kakuhle: Iphucula ukutyeba kunye nokuhamba kakuhle kwe-mortar kunye ne-tile adhesive, iqinisekisa ukusetyenziswa okuthambileyo kunye nokunamathela okukhuselekileyo.
Ukuphucula ukunamathela kunye neempawu zokungatyibiliki: Ukongeza i-HPMC kwi-adhesives zethayile kunye nomgubo we-putty kuthintela izinto ukuba zingatyibiliki ngexesha lokusetyenziswa ngokuthe nkqo, okuqinisekisa ukusetyenziswa ngokuchanekileyo. Ke ngoko, i-HPMC ibe sisongezelelo esisebenzayo esingenakutshintshwa kwiimortars zanamhlanje zomxube owomileyo zokwakha.
2. Amayeza
Kwishishini lezemithi, i-HPMC isetyenziswa kakhulu njengesixhobo sokuncedisa kunye nesixhobo esisebenzayo:
Izixhobo zokugquma iipilisi kunye ne-matrix: I-HPMC ingasetyenziswa njengesixhobo se-matrix kwiifomyula ezikhutshwayo ezilawulwayo, okuvumela ukukhululwa kwamayeza okuqhubekayo okanye okulawulwayo.
Izinto zokubopha iipilisi kunye neearhente zokwenza ifilimu: Ziqinisekisa ukwakheka kwepilisi okuzinzileyo kwaye zibonelela ngeempawu ezilungileyo zokuqhekeka.
Izinto zegobolondo lekhaphu: Iikhaphu zeHPMC, njengendlela esekwe kwizityalo, ziye zatshintsha kancinci kancinci ezinye iikhaphu zegelatin, nto leyo eyanelisa iimfuno zabantu abatya imifuno kunye nabo bane-allergy kwizithako zezilwanyana.
Iimpawu zazo ezingenabungozi, ezingacaphukisiyo, nezihambelanayo ne-bio zenza ukuba zikhuseleke kakhulu ekusetyenzisweni kwimixube yamayeza.
3. Iikhemikhali zemihla ngemihla
Kwishishini leekhemikhali lemihla ngemihla, i-HPMC, njengesithako se-polymer esisebenzayo, isetyenziswa kakhulu njengesithambisi, isizinzisi, kunye nesifunxi-manzi:
Kwishampu nakwijeli yeshawa: Iphucula ukutyibilika kunye nokunamathela eludongeni kwenkqubo, iphucula amava omsebenzisi.
Kwi-toothpaste: Isebenza njenge-binder kunye ne-stabilizer, iqinisekisa i-paste efanayo, engahlukanisiyo. Izinto zokuthambisa: Inika iipropati zokufumisa kunye nokwenza ifilimu kwiimaski zobuso kunye nee-lotions, ngelixa ikwaphucula imvakalelo egudileyo yemveliso.
Ezi zicelo zibonisa ixabiso elikhethekileyo le-HPMC ekuphuculeni ubume bemveliso kunye nozinzo.
4. Ishishini lokutya
I-HPMC isetyenziswa kakhulu kwishishini lokutya, njengesixhobo sokutyebisa, i-emulsifier, kunye ne-stabilizer:
Izinto Ezibhakiweyo: Zinceda ukugcina umswakama wokutya, ziphucula incasa, kwaye zandisa ixesha lokugcinwa.
Ukutya Okunamafutha Aphantsi: I-HPMC inokulinganisa indlela evakala ngayo emlonyeni yamafutha, inciphise iikhalori ngaphandle kokunciphisa incasa.
Iziselo kunye neemveliso zobisi: Zithintela ukwahlukana kunye nokubola kwengca, zigcina incasa efanayo.
Ngenxa yokhuseleko lwayo kunye neempawu zayo zokutyiwa, i-HPMC iqinisekiswe njengesongezelelo sokutya kumazwe amaninzi.
5. Ezinye izicelo
Ukongeza kwizicelo ezikhankanyiweyo apha ngasentla,I-HPMCikwadlala indima kwezi zinto zilandelayo:
Iingubo kunye neepeyinti: Njengesithambisi kunye nesiqinisi, iphucula ukusetyenziswa kwengubo kunye nozinzo lokugcina.
Iiceramics kunye neMetallurgy: Njengesixhobo sokuncedisa ukubumba, yongeza amandla omhlaba kwaye incede ekutshiseni. Ezolimo: Zisetyenziswa njengesixhobo sokuxhoma kunye nesibopheleli kwimixube yezibulali-zinambuzane ukuphucula ukusebenza kakuhle kwesi sidakamizwa ixesha elide.
Iiplastiki kunye nokulungiswa kwepolymer: Zisetyenziswa njengesinyibilikisi okanye njengesixhobo sokuncedisa ukuphucula ukusebenza kwemveliso.
Ngenxa yeempawu zayo ezizodwa zomzimba nezekhemikhali, i-hydroxypropyl methylcellulose (HPMC) ingene kakhulu kumashishini okwakha, amayeza, iikhemikhali zemihla ngemihla, ukutya, kunye namanye amashishini. Ayiphuculi kuphela ukusebenza kwemveliso kodwa ikwaphucula namava omsebenzisi kunye nokusebenza kakuhle kwemveliso. Njengoko imfuno yokhuseleko lokusingqongileyo, ukhuseleko, kunye nokusebenza kwayo isanda, iindawo zokusetyenziswa kwe-HPMC ziya kuqhubeka nokukhula, zibe sisisombululo esiphambili kumashishini amaninzi.
