Methyl hydroxyethyl cellulose (MHEC) ndi yofunika kwambiri yochokera ku cellulose ether, yomwe imagwiritsidwa ntchito kwambiri pomanga, zokutira, zoumba, zodzoladzola ndi mafakitale ena. Monga chowonjezera chogwira ntchito, MHEC imagwira ntchito yofunika kwambiri pazinthu zosiyanasiyana chifukwa cha kukhuthala bwino, kusunga madzi, kumamatira ndi kupanga mafilimu.
1. Kugwiritsa ntchito zipangizo zomangira
Muzomangira, MHEC imagwiritsidwa ntchito kwambiri mumatope owuma opangidwa ndi simenti ndi gypsum, makamaka ngati chowonjezera, chosungira madzi komanso chomangira. MHEC ikhoza kupititsa patsogolo ntchito yomanga matope, kupititsa patsogolo kusungirako madzi, ndikuletsa kuphulika kwamatope chifukwa cha kutaya madzi mofulumira. Kuphatikiza apo, MHEC imathanso kukonza zomatira ndi mafuta amatope, ndikupangitsa kuti zomangamanga zikhale zosavuta.
Mu zomatira za matailosi ndi ma grouts, kuwonjezera kwa MHEC kumatha kupititsa patsogolo ntchito zotsutsana ndi zinthuzo ndikuwonjezera nthawi yotsegulira, kupatsa ogwira ntchito yomanga nthawi yochulukirapo kuti asinthe. Panthawi imodzimodziyo, MHEC ikhozanso kupititsa patsogolo kukana kwa ming'alu ndi kukana kwa shrinkage ya wothandizira caulking kuonetsetsa kuti ntchito yake ikhale yokhazikika.
2. Kugwiritsa ntchito mumakampani opaka utoto
M'makampani opanga zokutira, MHEC imagwiritsidwa ntchito makamaka ngati thickener, stabilizer ndi emulsifier. Chifukwa MHEC ili ndi kukhuthala kwabwino kwambiri, imatha kuwongolera bwino ma rheology of zokutira, potero imapangitsa kuti zokutira zitheke komanso kusanja. Kuphatikiza apo, MHEC imathanso kukonza magwiridwe antchito a anti-sag a zokutira ndikuwonetsetsa kufanana ndi kukongola kwa zokutira.
Mu utoto wa latex, zinthu zosungira madzi za MHEC zimathandiza kupewa kutuluka kwamadzi mwachangu panthawi yowumitsa, potero kupewa kupezeka kwa zolakwika zapamtunda monga ming'alu kapena mawanga owuma. Panthawi imodzimodziyo, mafilimu abwino opanga mafilimu a MHEC amathanso kupititsa patsogolo kukana kwa nyengo ndi kukana kwa scrub, zomwe zimapangitsa kuti chovalacho chikhale cholimba.
3. Kugwiritsa ntchito mafakitale a ceramic
M'makampani a ceramic, MHEC imagwiritsidwa ntchito kwambiri ngati chothandizira ndikumangirira. Chifukwa cha kusungirako bwino kwa madzi komanso kukhuthala, MHEC imatha kupititsa patsogolo pulasitiki ndi mawonekedwe a thupi la ceramic, kupangitsa kuti zinthuzo zikhale zofananira komanso wandiweyani. Kuphatikiza apo, zomangira za MHEC zimathandizira kulimbitsa mphamvu ya thupi lobiriwira komanso kuchepetsa chiopsezo cha ming'alu panthawi ya sintering.
MHEC imagwiranso ntchito yofunikira pakuwala kwa ceramic. Sizingangowonjezera kuyimitsidwa ndi kukhazikika kwa glaze, komanso kuwongolera bwino komanso kufananiza kwa glaze kuonetsetsa kuti zinthu za ceramic zili pamwamba.
4. Kugwiritsa ntchito zodzoladzola ndi zinthu zosamalira anthu
MHEC imagwiritsidwanso ntchito kwambiri muzodzoladzola ndi zinthu zosamalira anthu, makamaka ngati zonenepa, zoziziritsa kukhosi, zolimbitsa thupi ndi opanga mafilimu. Chifukwa cha kufatsa kwake komanso kusakwiyitsa, MHEC ndiyoyenera kugwiritsidwa ntchito pazinthu zosamalira khungu monga zonona, mafuta odzola ndi oyeretsa nkhope. Ikhoza kuonjezera kugwirizana kwa mankhwala ndikuwongolera maonekedwe ake, kupanga mankhwalawo kukhala osavuta komanso osavuta kugwiritsa ntchito.
M'zinthu zosamalira tsitsi, mafilimu opanga mafilimu a MHEC amathandizira kupanga filimu yotetezera pamwamba pa tsitsi, kuchepetsa kuwonongeka kwa tsitsi ndikupatsa tsitsi kukhudza kosalala ndi kofewa. Kuphatikiza apo, zinthu zonyowa za MHEC zitha kukhalanso ndi gawo lotsekera m'madzi komanso kunyowetsa pazinthu zosamalira khungu, kukulitsa mphamvu yamadzi.
5. Mapulogalamu m'mafakitale ena
Kuphatikiza pa madera akuluakulu ogwiritsira ntchito omwe atchulidwa pamwambapa, MHEC imathandizanso kwambiri m'mafakitale ena ambiri. Mwachitsanzo, m'makampani opangira mafuta, MHEC imagwiritsidwa ntchito pobowola madzi ngati thickener ndi stabilizer kuti apititse patsogolo rheology yamadzimadzi obowola komanso kuthekera kwake kunyamula zodula. M'makampani opanga nsalu, MHEC imagwiritsidwa ntchito ngati chowonjezera chosindikizira phala, chomwe chingapangitse kumveka bwino komanso kuwala kwamitundu yosindikizidwa.
MHEC imagwiritsidwanso ntchito m'makampani opanga mankhwala monga binder ndi mafilimu opanga mapiritsi, omwe amatha kupititsa patsogolo mphamvu zamakina ndi maonekedwe a mapiritsi. Kuphatikiza apo, m'makampani azakudya, MHEC imagwiritsidwanso ntchito ngati thickener ndi emulsifier popanga zokometsera, zakumwa ndi mkaka kuti zithandizire kukoma ndi kukhazikika kwa mankhwalawa.
Methylhydroxyethylcellulose (MHEC) yakhala ikugwiritsidwa ntchito kwambiri pomanga, zokutira, zoumba, zodzoladzola ndi mafakitale ena chifukwa cha kukhuthala bwino, kusunga madzi, zomatira komanso kupanga mafilimu. Ndi kupita patsogolo kwaukadaulo komanso kusiyanasiyana kwa zofuna za msika, magawo ogwiritsira ntchito a MHEC akukulirakulirabe, ndipo kufunikira kwake m'mafakitale osiyanasiyana kudzawonekera kwambiri.
