Hydroxypropyl Methylcellulose (HPMC)imhando ye non-ionic cellulose ether inoshandiswa zvakanyanya muzvivakwa, mishonga, chikafu, zvizoro, zvigadzirwa zvekuchenesa uye mamwe maindasitiri. Yakagadzirwa nezvinhu zvechisikigo zvepolymer (senge donje) kuburikidza nekurapa ne alkali uye etherification reaction, uye ine hunyoro hwakanaka, kuchengetedza mvura, kugadzira firimu, kubatana, mafuta uye kugadzikana.
1. Kushandiswa muindasitiri yekuvaka
1.1. Dhaka rakasanganiswa nevhu rakaoma
Imwe yenzvimbo dzinonyanya kushandiswa neHPMC muindasitiri yekuvaka idhaka rakasanganiswa nemvura, senge tile adhesive, masonry mortar, self-leveling mortar, plastering mortar, nezvimwewo. Inonyanya kuita mabasa anotevera:
Kuchengetwa kwemvura: Kunodzivirira mvura iri mu simende kuti isamhanye nekukurumidza, izvo zvinoita kuti simende iwane mvura yakakwana uye zvinovandudza simba rekubatanidza.
Inovandudza mashandiro ekuvaka: Inopa kuyerera kwakakodzera uye mafuta, zvichiita kuti dhaka rive nyore kushandisa uye inoderedza kuramba kupomba.
Kushanda kwekudzivirira kutsvedza: Kunodzivirira mataira kuti asatsvedzerere pasi nechinamira chemataira uye kunovandudza kushanda zvakanaka kwekuvaka.
1.2. Zvigadzirwa zveGypsum
Mumaplaster akagadzirwa negypsum kana macaulking agents, HPMC inogona kuvandudza zvakanyanya kuchengetedza mvura uye mashandiro ayo ekuvaka, kuderedza kutsemuka, uye kugadzirisa kupenya kwenzvimbo.
1.3. Sisitimu yekudzivirira yekunze (EIFS)
HPMC inoshandiswa mukugadzira dhaka rekudzivirira kupisa uye dhaka rinodzivirira kupwanyika kuti rivandudze kupwanyika kwaro, kuwedzera kunamira uye hunhu hwekudzivirira kupwanyika, uye kuona kuti system yekudzivirira kupisa inogara kwenguva refu.
2. Kushandiswa muindasitiri yemishonga
HPMC mushonga unozivikanwa pasi rose une simba rekushandisa mishonga uye haukuvadzi chepfu. Unonyanya kushandiswa pa:
Zvinhu zvinogadzira firimu remishonga inoburitswa kwenguva refu: kugadzira firimu rakatetepa pamusoro pemapiritsi kudzora huwandu hwemushonga unoburitswa.
Kapusule shell zvinhu: sezvinhu zvisina kugadzirwa zvemakapusule emiti, isarudzo yakanaka kune vanodya miriwo chete nevanhu vanonamata.
Zvinonamira uye zvinonamira: zvinoshandiswa mumadonhwe emaziso, majeli, mafuta emumaziso nezvimwe zvigadzirwa.
3. Kushandiswa muindasitiri yechikafu
Mukugadzira chikafu, HPMC, sechinowedzera chikafu (E464), ine mabasa anotevera:
Emulsifier stabilizer: inoshandiswa muzvinwiwa zvakasanganiswa, kirimu nezvimwe zvigadzirwa kuchengetedza kugadzikana kwe emulsification.
Chinhu chinochengetedza mvura uye chinogocha: chinoshandiswa muchingwa, makeke, manoodles ekukurumidza kuvandudza chimiro chenyama uye kuwedzera nguva yekushanda kwayo.
Chinotsiva mafuta ane macalorie mashoma: chinoshandiswa kutsiva chikamu chemafuta muzvikafu zvine mafuta mashoma kuti kunakidze kunaka pasina kuwedzera macalorie.
4. Kushandiswa mumakemikari ezuva nezuva uye zvigadzirwa zvekuchenesa
HPMC inoita mabasa anotevera mu shampoo, gel yekugeza, sipo yemaoko, uye sipo yekuwachisa mbatya:
Kukora kwechinhu: kunatsiridza kunaka kwechigadzirwa uye kupa rheology yakakwana.
Basa rekugadzira firimu uye kunyorovesa: gadzira firimu rekudzivirira pamusoro peganda kuti uchengetedze hunyoro.
Kuvandudza kugadzikana kwefuro: wedzera kupfava uye kugara kwenguva refu kwefuro.
5. Kushandiswa muindasitiri yemafuta nekugadzira mbatya
5.1. Kuchera mafuta munzvimbo dzeoiri
HPMC, sechinowedzerwa chemvura inoboorwa, inogona kuita mabasa anotevera:
Kukora: kuvandudza rheology yematope.
Chinhu chinochengetedza mvura: kuderedza kurasikirwa nekusefa uye kuchengetedza chimiro chemadziro etsime.
5.2. Kuputira kwakavakirwa mumvura
Mumachira ekudzivirira, HPMC inoshandiswa semuchina wekuomesa, wekuparadzanisa uye we emulsifier, ine simba rakanaka rekudzivirira kupwanyika uye hunhu hwekuenzanisa mavakirwo, zvichiita kuti chirairo chive chakafanana uye chakapfava.
6. Kushandiswa muzviumbwa zvesimbi nedzimwe nzvimbo
Mukuita kwekubvisa nekuumba zveceramic, HPMC inoshandiswa semubati uye chinhu chinochengetedza mvura kuti ivandudze simba renzvimbo isina chinhu uye kudzivirira kutsemuka.
HPMC inoshandiswawo muindasitiri yefodya, kugadzira mapepa, kudhinda nekudhaya machira, kurima (sekumisa mishonga yezvipembenene, kuputira mbeu) nedzimwe nzvimbo, ichiratidza kugona kwayo kuchinjika uye kuchinjika.
Hydroxypropyl methylcellulose chinhu chepolymer chine mashandiro akanaka uye chinoshandiswa zvakasiyana-siyana. Hunhu hwayo husina chepfu, hune hushamwari kune nharaunda uye hunogona kushandiswa zvakasiyana-siyana hunoita kuti ive chinhu chakakosha muindasitiri dzakawanda. Kuramba ichiwedzerwa kwekushandiswa kwayo mumabasa ekuvaka, mishonga, chikafu, makemikari ezuva nezuva, machira, nezvimwewo kwakasimudzirawo kuvandudzwa nekusimudzirwa kwetekinoroji yechigadzirwa chayo. Mune ramangwana, nekudiwa kuri kuwedzera kwezvinhu zvakasvibira uye zvine hushamwari kune nharaunda,Mikana yekushandiswa kweHPMC ichave yakakura.
