Hydroxypropyl methylcellulose (HPMC)imhando ye cellulose ether isina ionic yakagadzirwa ne cellulose yemhando ye polymer kuburikidza nekugadzirwa kwemakemikari akasiyana-siyana. Iupfu huchena husina hwema, husina kunaka uye husina chepfu hunozvimba mumvura inotonhora kusvika pakuita colloidal solution yakajeka kana ine madzerere zvishoma. Hune hunhu hwekukora, kusunga, kuparadzira, emulsifying, kugadzira firimu, kumisa, kukwiza, gelling, hunhu hwepamusoro, kuchengetedza hunyoro uye ma colloid anodzivirira. Hydroxypropyl methylcellulose, methylcellulose inogona kushandiswa muzvivakwa, indasitiri yekuputira, synthetic resin, indasitiri yeceramics, mishonga, chikafu, machira, kurima, makemikari ezuva nezuva nemamwe maindasitiri.
Kushandiswa kukuru kwehydroxypropyl methylcellulose HPMC muzvinhu zvekuvaka:
1 Grout yekupurasita yakagadzirwa nesimende
①Vandudza kufanana, ita kuti plastering paste ive nyore kuipurasita, wedzera kuramba kudonha, wedzera kuyerera uye kupomba, uye wedzera kushanda zvakanaka.
②Kuchengetedza mvura yakawanda, kunowedzera nguva yekuisa dhaka, kuvandudza mashandiro ebasa, uye kuita kuti dhaka rive nyore kunyorova uye kusimba kuti rigadzire simba rakawanda remuchina.
③ Dzora kupinda kwemhepo kuti ubvise mitswe pamusoro pechifukidziro uye ugadzire nzvimbo yakatsetseka yakakwana.
2 mapurasitiki ekuisa plaster akagadzirwa negypsum uye zvigadzirwa zvegypsum
①Vandudza kufanana, ita kuti plastering paste ive nyore kuipurasita, wedzera kuramba kudonha, wedzera kuyerera uye kupomba, uye wedzera kushanda zvakanaka.
②Kuchengetedza mvura yakawanda, kunowedzera nguva yekuisa dhaka, kuvandudza mashandiro ebasa, uye kuita kuti dhaka rive nyore kunyorova uye kusimba kuti rigadzire simba rakawanda remuchina.
③ Dzora kuenderana kwesimbi kuti ive yakafanana uye gadzira chifukidziro chakakodzera pamusoro.
3 Dura rekugadzira masonry
①Simbisa kunamira pamusoro pemadziro, wedzera kuchengetedza mvura, uye wedzera kusimba kwemota.
②Vandudza kunyorova uye purasitiki, uye wedzera kushanda; dhaka rakavandudzwa ne cellulose ether riri nyore kuvaka, rinochengetedza nguva yekuvaka uye rinoderedza mari yekuvaka.
③Ether ine cellulose inochengetedza mvura yakawanda, yakakodzera zvidhinha zvinonwisa mvura yakawanda.
4 ndiro yekuzadza majoini
①Inochengetedza mvura zvakanaka, inowedzera nguva yekuvhura uye inovandudza mashandiro ebasa. Inozora mafuta akawanda, iri nyore kusanganisa.
②Vandudza kuramba kudonha uye kuramba kutsemuka, uye kuvandudza kunaka kwependi yepamusoro.
③Vandudza kunamira kwenzvimbo inosungirirwa uye kupa magadzirirwo akatsetseka uye akapfava.
Zvinonamira Mataira zvishanu
①Sanganisa zviri nyore kuomesa, hapana mapundu achabuda, kumhanya kwekushandisa kuchawedzerwa, mashandiro ekuvaka achavandudzwa, nguva yekushanda ichachengetedzwa, uye mari yekushanda ichaderedzwa.
②Nekuwedzera nguva yekuvhura, zvinovandudza kushanda zvakanaka kwekuisa mataira uye zvinopa mukana wakanaka wekunamatira.
6 Zvinhu zvepasi zvinozvienzanisa
① Inopa kusimba uye inogona kushandiswa semushonga wekudzivirira kugadzikana.
②Simudza kupomba kwemvura uye wedzera kushanda zvakanaka kwekugadzira matombo.
③ Dzora kuchengetwa kwemvura uye kuderera kwevhu kuti uderedze kutsemuka nekuderera kwevhu.
7 Pendi inobva mumvura
①Dzivirira kunaya kwemvura kwakasimba uye kuwedzera nguva yechigadzirwa mugaba. Kugadzikana kwakanyanya kwehupenyu uye kubatana kwakanaka nezvimwe zvikamu.
②Vandudza kuyerera kwemvura, ipai kudzivirira kupwanyika kwemvura, inodzivirira kudonha kwemvura uye kuenzana kwayo, uye iva nechokwadi chekuti pamusoro payo panopera zvakanaka.
8 upfu hwemapepa emadziro
①Nyungudutsa nekukurumidza pasina kuungana, izvo zviri nyore kusanganisa.
②Ipa simba rakasimba rekubatana.
9 Bhodhi resimende rakaburitswa
①Ine kunamira kwakanyanya uye ine mafuta akawanda, uye inowedzera kugona kwekugadzirwa kwezvinhu zvakaburitswa.
②Simbisa simba regirini, wedzera kunyorova kwemvura uye kupora, uye wedzera goho.
Zvigadzirwa gumi zveHPMC zvedhaka rakasanganiswa
IyoHPMCChigadzirwa chinoshandiswa zvakanyanya padhaka rakasanganiswa kare chine mvura iri nani pane zvigadzirwa zvakajairika mudhaka rakasanganiswa kare, zvichiita kuti zvinhu zvisina kugadzirwa zve cementitious zvinyatso nyorova, uye zvinodzivirira zvakanyanya kuderera kwesimba rekubatana kunokonzerwa nekuoma kwakanyanya uye kutsemuka kunokonzerwa nekuoma. HPMC inewo simba rekuisa mhepo. Zvigadzirwa zveHPMC zvinoshandiswa zvakanyanya padhaka rakasanganiswa kare zvine mhepo yakakodzera, yakafanana uye diki, izvo zvinogona kuvandudza simba uye kupurasita kwedhaka rakasanganiswa kare. Chigadzirwa cheHPMC chinoshandiswa zvakanyanya padhaka rakasanganiswa kare chine simba rekunonoka, izvo zvinogona kuwedzera nguva yekuvhurwa kwedhaka rakasanganiswa kare uye kuderedza kuoma kwekuvaka. Hydroxypropyl methylcellulose (HPMC) i-non-ionic cellulose ether yakagadzirwa kubva ku cellulose yepolymer yechisikigo kuburikidza nekugadzirwa kwemakemikari. Ihupfu huchena husina hwema, husina kunaka uye husina chepfu hunozvimba mumvura inotonhora kusvika pakuita colloidal solution yakajeka kana ine hutsi zvishoma. Ine hunhu hwekukora, kusunga, kuparadzira, emulsifying, kugadzira firimu, kumisa, kunyudza, kukwiza, kuchenesa, kuchengetedza hunyoro uye ma colloids anodzivirira. Hydroxypropyl methylcellulose, methylcellulose inogona kushandiswa muzvivakwa, indasitiri yekuputira, resin yekugadzira, indasitiri yeceramics, mishonga, chikafu, machira, kurima, makemikari ezuva nezuva nemamwe maindasitiri.
