I-Hydroxypropyl Methylcellulose (HPMC) yi-ether ye-cellulose engekho eyenziwe kusuka ku-Natural Polymer Matelioser cellulose ngochungechunge lwezinqubo zamakhemikhali. Bangamaphunga, angenambisi futhi angenambiseki omhlophe we-powder emhlophe egcwele isixazululo esicacile noma esinamafu kancane emanzini abandayo. Inokuqina, ukubopha, ukusabalalisa, ukuhambisa, ukwakha amafilimu, ukumisa amafilimu, ukumisa ama-adsorbing, ukugada, indawo esebenzayo ye-colloid ye-colloid. I-Hydroxypropyll Methylcellose kanye ne-methylcellulose zingasetshenziswa ezintweni zokwakha, imboni yokupenda, i-sonthetic resin, imboni ye-ceramic, umuthi, izindwangu, izimboni kanye nezimboni zansuku zonke.
Ifomula yamakhemikhali:
I-Hydroxypropylmethylcelleltelcelcellellulose (HPMC) [C6h7O2 (oh) 3-MN (OCH3) m (OCH2CH (OH) CH3) N] x
Ukusetshenziswa okuyinhloko kwe-hydroxypropyllylylyl methylcellulose hpmc ezintweni zokwakha:
1. Usimende osuselwa kuso
⑴ Thuthukisa ukufana, yenza ukulungiswa kokulungisa kube lula ukudonsa, kuthuthukise ukumelana nokuqina, ukuthuthukisa ukuncipha kanye nokuphazamiseka, futhi kuthuthukise ukusebenza kahle komsebenzi.
Ukugcinwa kwamanzi amaningi, ukunweba isikhathi sokugcina sodaka, ukwenza ngcono umsebenzi wokusebenza, kanye nokwenza lula i-hydration kanye nokuqina kodaka ukukhiqiza amandla aphezulu okusebenza.
⑶ Lawula ukwethulwa komoya ukuze ususe imifantu ku-coating ebusweni futhi wakhe indawo enhle ebushelelezi.
2. I-gypsum-based plaster kanye nemikhiqizo ye-gypsum
⑴ Thuthukisa ukufana, yenza ukulungiswa kokulungisa kube lula ukudonsa, kuthuthukise ukumelana nokuqina, ukuthuthukisa ukuncipha kanye nokuphazamiseka, futhi kuthuthukise ukusebenza kahle komsebenzi.
Ukugcinwa kwamanzi amaningi, ukunweba isikhathi sokugcina sodaka, ukwenza ngcono umsebenzi wokusebenza, kanye nokwenza lula i-hydration kanye nokuqina kodaka ukukhiqiza amandla aphezulu okusebenza.
⑶ Lawula ukungaguquguquki kodaka ukuze wakhe i-coating engaphezulu komhlaba.
3
⑴ Thuthukisa ukunamathela nge-masonry ebusweni, uthuthukise ukugcinwa kwamanzi, futhi uthuthukise amandla odaka.
⑵ Thuthukisa ukulambisa kanye ne-plastiki, futhi uthuthukise ukwakhiwa; Udaka olwenziwe ngcono yiCellulose Ether kulula ukwakha, ukusindisa isikhathi sokwakha futhi wehlise izindleko zokwakha.
⑶ Ultra-high-ether ether, elungele izitini ezingena emanzini aphezulu.
4. Iphaneli ehlanganyelwe
Ukugcinwa kwamanzi, ukwelula isikhathi sokuvula futhi kuthuthukise ukusebenza kahle komsebenzi. Ukugcoba okuphezulu, okulula ukuxubana. ⑵ Thuthukisa ukumelana nokuqina kwe-shrinkage kanye nokumelana nokuqhekeka, Thuthukisa ikhwalithi ephezulu yokuhlanganisa. ⑶ Thuthukisa ukunamathela kwe-bonding ebusweni futhi unikeze ukuthungwa okubushelelezi nokubushelelezi.
5 ⑵ Ngokwandisa isikhathi sokuvula, ukusebenza kahle kwe-tiling kungathuthukiswa futhi umphumela omuhle kakhulu wokunamathela ungahlinzekwa.
I-6 Izinto zokuzenzela phansi zonaphansi ⑵enzance ukuncipha kobubi futhi kuthuthukise ukusebenza kahle kokuvula umhlabathi. ⑶ Lawula ukugcinwa kwamanzi kanye nokuqothuka, kunciphise imifantu kanye ne-shrinkage yomhlaba.
7 Ukuqina okuphezulu kwebhayoloji, ukuhambisana okuhle nezinye izinto. ⑵ Thuthukisa u-Fluity, ahlinzeke nge-anti-splash enhle, i-anti-sagging kanye nokulinganisa izakhiwo, futhi uqinisekise ukuqedwa komhlaba omuhle kakhulu.
8. Wallpaper Powder ⑴ Chaza ngokushesha ngaphandle kwama-lumps, amahle ngokuxuba. ⑵ Nikeza amandla amakhulu ebhondi.
I-9 ⑵ Thuthukisa amandla aluhlaza, ukukhuthaza i-hydration kanye nomphumela wokuphula umthetho, futhi wandise isivuno.
10. Imikhiqizo ye-HPMC enikezelwe imikhiqizo elungiselelwe ngohlobo lwe-Mortar HPMC enikezelwe udaka olulodwa oluhlanganiswe nodaka lwamanzi olungcono kudoti ojwayelekile, uvimbela kakhulu ukuncishiswa kwamandla ebhondi okubangelwa ukomisa ngokweqile, futhi imifantu ebangelwa ukomisa i-shrinkage. I-HPMC nayo inomphumela othile wokufaka umoya. Umkhiqizo we-HPMC osetshenziselwa udaka oluhlanganisiwe olunemali enesilinganiso esifanelekile sokungena komoya, umfaniswano kanye namabhamuza womoya omncane, ongawathuthukisa amandla nokuvuselelwa kodaka okulungiselelwe. Umkhiqizo we-HPMPC osetshenziselwa udaka oluxutshwe ngohlobo oluhlanganisiwe unomphumela othile wokubuyisa, onganweba isikhathi sokuvula sodaka oluselungiselelwe futhi sinciphise ubunzima bokwakha.
