I-Hydroxypropylmethylcellulose (HPMC) i-polymer yokwenziwa esetyenziswa kakhulu kwishishini lokwakha, ngakumbi kwimveliso yodaka kunye nekhonkrithi. I-HPMC isebenza njenge-ejenti ye-thickener kunye nokugcinwa kwamanzi, iphucula iimpawu zoomatshini kunye nokusebenza kwemathiriyeli esekwe kwisamente. I-HPMC sisithako esisebenza ngeendlela ezininzi esinokusetyenziswa kwiimveliso zesamente ezifana neethayile, iiplates kunye nemigangatho. Kweli nqaku, siphonononga izibonelelo zokusebenzisa i-HPMC kudaka kunye nezicelo zekhonkrithi.
Ukuphucula ukusebenza
Ukongezwa kwe-HPMC kudaka kunye nekhonkrithi kuphucula iplastiki, ukudibanisa kunye nokugcinwa kwamanzi kwimixube yesamente. I-HPMC idumba emanzini kwaye yenza ubunzima obufana nejeli, okunciphisa ukulahlekelwa kwamanzi kumxube, okuvumela ukuba i-samente ihlale isebenza ixesha elide. Ukuphuculwa kokusebenza komxube kwenza kube lula kubasebenzi ukuba bafake umxube wesamente kwindawo egudileyo, efanayo.
ukwandisa ukunamathela
Ukongezwa kwe-HPMC kukwaphucule ukunamathela komxube wesamente kwi-substrate. I-HPMC isebenza njenge-adhesive phakathi kwe-substrate kunye nomxube we-cementitious, iqinisekisa ibhondi eyomeleleyo kunye nexesha elide. Ukunamathela okuphuculweyo komxube we-samente kunciphisa amathuba okuqhekeka okanye ukuchithwa kodaka okanye umaleko wekhonkrithi.
ukunciphisa ukucutheka
I-shrinkage yinto eyenzekayo xa amanzi ephuma kumxube wesamente ebangela ukuba acutheke. Oku kunokukhokelela ekuqhekekeni kunye nezikhewu kuluhlu lwesamente, ukunciphisa ingqibelelo yesakhiwo sesakhiwo. Ukongeza i-HPMC kwimixube yesamente kunciphisa ukucutheka komxube ngokugcina ukufuma kunye nokunciphisa izinga lokunyuka kwamanzi. Oku kuqinisekisa ukuba umxube we-samente uhlala uzinzile kwaye awunciphisi, okubangelwa isakhiwo esinamandla kunye nesigxina sokwakha.
Ukonyuka kokuqina
Ukusebenzisa i-HPMC kwimixube yesamente kunokuphucula ukuqina kwemveliso egqityiweyo. I-HPMC yenza uthungelwano lwesibini ngaphakathi kwe-matrix yesamente, iphucula amandla kunye nokuqina kwekhonkrithi. Ijeli efana nejeli eyenziwe yi-HPMC iphinda isebenze njengoluhlu olukhuselayo, ukuthintela ukungena kwamanzi kunye nezinye izinto ezinobungozi ezinokubangela umonakalo kwizakhiwo eziphathekayo.
Ukuphucula ukuxhathisa kwamanzi
Ukumelana namanzi yinto ephambili yezakhiwo ezisekelwe kwisamente, ngakumbi apho zibonakaliswe emanzini okanye kumswakama. I-HPMC yongeza ukuxhathisa kwamanzi kwimixube yesamente ngokwenza umqobo othintela amanzi ukuba angangeni kwimatrix yesamente. Oku kunciphisa ithuba lomonakalo wamanzi njengokuqhekeka, ukubola kunye nokubola, ukuqinisekisa ukuba isakhiwo esihlala ixesha elide, esihlala sihlala.
ukwandisa ukuguquguquka
Ukusetyenziswa kwe-HPMC kwandisa ukuguquguquka komxube wesamente. I-HPMC inciphisa ukuqina kwekhompawundi, ivumela ukuba igobe kwaye yandise ngaphandle kokuqhekeka okanye ukuqhekeka. Oku kwenza ukuba ulwakhiwo lwekhonkrithi luxhathise ngakumbi ukothuka kunye nokungcangcazela, ukunciphisa ukwenzeka komonakalo kumandla angaphandle.
Ukuphucula impembelelo yokusingqongileyo
Ukusebenzisa i-HPMC kwimixube yesamente nako kunempembelelo entle kokusingqongileyo. I-HPMC yinto engeyiyo ityhefu, i-biodegradable kwaye ihambelana nokusingqongileyo engenzi naziphi na iingozi kwimpilo okanye kokusingqongileyo. Ukusebenzisa i-HPMC kwizicelo ezisekelwe kwisamente kunokunciphisa umthamo wamanzi afunekayo kumxube, ukunciphisa ukusetyenziswa kwamanzi kunye nokunciphisa impembelelo yokusingqongileyo.
ukuququmbela
Ukongezwa kwe-hydroxypropylmethylcellulose (HPMC) kwidaka kunye nemixube yekhonkrithi ibonelela ngeenzuzo ezininzi ngokuphucula iimpawu zomatshini kunye nokusebenza komxube. I-HPMC iphucula ukusebenza kwemixube yesamente ngokuphucula iplastiki, ukuhlangana kunye nokugcinwa kwamanzi, okubangela ukuba kube lula, ukufana okufanayo. I-HPMC iphinda iphucule ukunamathela, inciphisa ukushwabana, iphucula ukuqina, ukumelana namanzi kunye nokuguquguquka, ngelixa inciphisa impembelelo yokusingqongileyo yenkqubo. Ngoko ke, ukusetyenziswa kwe-HPMC kushishino lokwakha linyathelo elibalulekileyo elibhekiselele kwizakhiwo ezisebenzayo, ezizinzileyo kunye nezihlala ixesha elide ezisekelwe kwisamente ezinokumelana neemeko ezahlukeneyo.
