Kodi hydroxypropyl methyl cellulose ndi chiyani?

Hydroxypropyl methyl cellulose (HPMC), yomwe imadziwikanso kuti hydroxypropyl methylcellulose, cellulose hydroxypropyl methyl ether, cellulose, 2-hydroxypropylmethyl ether, PROPYLENE GLYCOL ETHER OF METHYLCELLULOSE, CAS No. 9004-65-3, imapangidwa kuchokera ku cellulose ya thonje yoyera kwambiri pogwiritsa ntchito etherification yapadera pansi pa mikhalidwe ya alkaline. HPMC ikhoza kugawidwa m'magulu a nyumba, kalasi ya chakudya ndi kalasi ya mankhwala malinga ndi momwe imagwiritsidwira ntchito. Imagwiritsidwa ntchito kwambiri pa zomangamanga, chakudya, mankhwala ndi zodzoladzola, mankhwala a tsiku ndi tsiku ndi mafakitale ena.

Kodi ntchito za HPMC ndi ziti?

Makampani omanga

1. Simenti yopangira miyala
Kulimbitsa kumatirira pamwamba pa miyala yamtengo wapatali kungathandize kusunga madzi, motero kulimbitsa mphamvu ya matope, komanso kukonza mafuta ndi pulasitiki kuti ntchito yomanga iyende bwino. Kapangidwe kosavuta kamasunga nthawi ndikuwonjezera kugwiritsa ntchito bwino ndalama.
2. Zinthu zopangidwa ndi gypsum
Zingathe kutalikitsa nthawi yogwira ntchito ya matope ndikupanga mphamvu zambiri zamakanika panthawi yolimba. Chophimba chapamwamba kwambiri chimapangidwa powongolera kusinthasintha kwa matope.
3. Chochotsera utoto ndi utoto chochokera m'madzi
Imatha kutalikitsa nthawi yosungiramo zinthu mwa kupewa mvula yambiri, ndipo imagwirizana bwino kwambiri komanso imakhala yolimba kwambiri. Kusungunuka kwake kumakhala kofulumira komanso kosavuta kusonkhana, zomwe zimathandiza kuti njira yosakaniza ikhale yosavuta. Imapanga makhalidwe abwino oyenda, kuphatikizapo kutayikira pang'ono komanso kusanjikizana bwino, kuonetsetsa kuti pamwamba pake pamakhala bwino, komanso kupewa kutsika kwa utoto. Wonjezerani kukhuthala kwa utoto wochotsa utoto wochokera m'madzi ndi utoto wosungunuka wa organic, kuti utoto wochotsa utoto usatuluke pamwamba pa ntchito.
4. Chomatira cha matailosi a ceramic
Zosakaniza zouma zimakhala zosavuta kusakaniza ndipo sizimasonkhana pamodzi, zomwe zimasunga nthawi yogwira ntchito chifukwa zimagwiritsidwa ntchito mwachangu komanso moyenera, zomwe zimapangitsa kuti zinthu zisamawonongeke komanso kuchepetsa ndalama. Zimathandizira kuti matailosi azigwira ntchito bwino komanso zimamatirira bwino powonjezera nthawi yozizira.
5. Zipangizo zodzipangira pansi
Imapereka kukhuthala ndipo ingagwiritsidwe ntchito ngati chowonjezera choletsa kutsekeka kuti ithandize kukonza bwino pansi. Kulamulira kusunga madzi kungachepetse kwambiri ming'alu ndi kufupika.
6. Kupanga miyala ya konkire yopangidwa
Zimathandizira kuti zinthu zotulutsidwa zigwire ntchito mosavuta, zimakhala ndi mphamvu yolimba komanso mafuta ambiri, komanso zimathandizira kuti mapepala otulutsidwa azikhala olimba komanso ogwirizana.
7. Chodzaza mbale
Hydroxypropyl methyl cellulose imakhala ndi madzi abwino kwambiri, imatha kukulitsa nthawi yozizira, ndipo mafuta ake ambiri amapangitsa kuti ntchitoyo ikhale yosalala. Imawongolera bwino mawonekedwe a pamwamba, imapereka mawonekedwe osalala komanso ofanana, komanso imapangitsa kuti malo olumikizirana akhale olimba kwambiri.
8. Gypsum yopangidwa ndi simenti
Ili ndi madzi ambiri osungira, imawonjezera nthawi yogwira ntchito ya matope, ndipo imathanso kuwongolera kulowa kwa mpweya, motero imachotsa ming'alu yaying'ono ya utoto ndikupanga malo osalala.

Makampani ogulitsa zakudya

1. Zipatso za citrus zophikidwa mu m'zitini: kupewa kuyera ndi kuwonongeka chifukwa cha kuwonongeka kwa ma glycosides a citrus panthawi yosungidwa, kuti zisunge bwino.
2. Zipatso zozizira: zimawonjezeredwa ku madzi a zipatso ndi ayezi kuti kukoma kukhale bwino.
3. Msuzi: umagwiritsidwa ntchito ngati cholimbitsa madzi kapena chokhuthala cha msuzi ndi phala la phwetekere.
4. Kuphimba ndi kupukuta madzi ozizira: kumagwiritsidwa ntchito posungira nsomba zozizira kuti zisasinthe mtundu ndi kuwonongeka kwa ubwino. Mukamaliza kupukuta ndi kupukuta ndi methyl cellulose kapena hydroxypropyl methyl cellulose aqueous solution, muzizire pa ayezi.
5. Chomatira cha mapiritsi: Monga chomatira chopangira mapiritsi ndi tinthu tating'onoting'ono, chimakhala ndi "kugwa kwabwino nthawi imodzi" (kusungunuka mwachangu, kugwa ndi kufalikira mukamamwa).

Makampani opanga mankhwala

1. Kutsekereza: Chothandizira kutsekereza chimapangidwa kukhala yankho la organic solvent kapena yankho lamadzi loperekera mapiritsi, makamaka potsekereza tinthu tokonzedwa.
2. Choletsa kuchedwa: magalamu 2-3 patsiku, 1-2G nthawi iliyonse, kwa masiku 4-5.
3. Mankhwala a maso: Popeza mphamvu ya osmotic ya methyl cellulose aqueous solution ndi yofanana ndi ya misozi, siimayambitsa kukwiya kwambiri m'maso. Imawonjezeredwa mu mankhwala a maso ngati mafuta okhudzira maso.
4. Jeli: Amagwiritsidwa ntchito ngati maziko a jeli monga mankhwala akunja kapena mafuta odzola.
5. Chothandizira kuyika m'mimba: chimagwiritsidwa ntchito ngati chokhuthala komanso chosungira madzi.

Makampani okongoletsa

1. Shampoo: Imawonjezera kukhuthala ndi kukhazikika kwa thovu la shampu, chotsukira ndi sopo.
2. Mankhwala otsukira mano: onjezerani kusinthasintha kwa mankhwala otsukira mano.

Makampani a uvuni

1. Zipangizo zamagetsi: monga guluu wopangira makina osindikizira a ceramic electric compactor ndi ferrite bauxite magnet, ingagwiritsidwe ntchito limodzi ndi 1.2-propanediol.
2. Mankhwala a glaze: amagwiritsidwa ntchito ngati mankhwala a glaze ochokera ku ziwiya zadothi komanso kuphatikiza ndi utoto wa enamel, zomwe zingathandize kuti zinthu zigwirizane bwino komanso kuti zinthu zisamawonongeke.
3. Dothi losagwira ntchito: Likhoza kuwonjezeredwa ku matope a njerwa osagwirizana kapena zinthu zogwiritsidwa ntchito mu uvuni kuti liwongolere kusungunuka kwa madzi ndi kusunga madzi.

Makampani ena

HPMC imagwiritsidwanso ntchito kwambiri mu utomoni wopangidwa, petrochemical, ceramics, kupanga mapepala, zikopa, inki yochokera m'madzi, fodya ndi mafakitale ena. Imagwiritsidwa ntchito ngati chokhuthala, chosungunula, chomangirira, chosakaniza ndi chokhazikika m'makampani opanga nsalu.

Kodi mungadziwe bwanji mtundu wa hydroxypropyl methyl cellulose (HPMC) m'njira yowoneka bwino?

1. Chromaticity: ngakhale kuti singathe kuzindikira mwachindunji ngati HPMC ndi yosavuta kugwiritsa ntchito, ndipo ngati choyeretsera chiwonjezeredwa popanga, ubwino wake udzakhudzidwa. Komabe, zinthu zabwino kwambiri zatsala pang'ono kugulidwa.
2. Kusalala: HPMC ili ndi ma meshes 80 ndi ma meshes 100 nthawi zonse, ndipo ma meshes 120 ndi ochepa. Ma HPMC ambiri ali ndi ma meshes 80. Nthawi zambiri, kusalala kwa offside ndikwabwino.
3. Kutumiza kuwala: perekani hydroxypropyl methyl cellulose (HPMC) m'madzi kuti apange colloid yowonekera bwino, kenako ndikuwona momwe kuwala kumayendera. Kuchuluka kwa kuwala, kumakhala bwino, zomwe zikusonyeza kuti mulibe zinthu zambiri zosasungunuka.
4. Mphamvu yokoka: Mphamvu yokoka ikalemera kwambiri, imakhala yabwino kwambiri. Chiŵerengerocho chimakhala chachikulu, makamaka chifukwa chakuti hydroxypropyl ili ndi zambiri. Ngati hydroxypropyl ili ndi zambiri, kusunga madzi kumakhala bwino.
Hydroxypropyl methyl cellulose ndi yokhazikika ku ma acid ndi ma bases, ndipo yankho lake lamadzi ndi lokhazikika kwambiri pa pH=2~12. Ndife opanga akatswiri. Ngati mukufuna izi, mutha kulumikizana nafe. Ndizo zonse zomwe tikufuna kugawana HPMC munkhaniyi. Ndikukhulupirira kuti zingakuthandizeni kumvetsetsa HPMC.
