Hydroxyethyl Methyl Cellulose Bakeng sa Kaho

Hydroxyethyl Methyl Cellulose, kapa HEMC, ke motsoako o nang le mekhoa e mengata e seng e ntse e tsebahala haholo indastering ea kaho. Ke polima e qhibilihang ka metsing e nkiloeng ho selulose 'me hangata e sebelisoa e le ntho e tiisang le e tlamang lits'ebetsong tse fapaneng, joalo ka seretse, li-grouts le samente. HEMC e boetse e tsejoa e le methyl hydroxyethyl cellulose (MHEC) kapa methyl hydroxypropyl cellulose (MHPC) mme e fumaneha ka limaraka tse fapaneng, e 'ngoe le e 'ngoe e na le thepa le litšobotsi tse itseng.

Sehloohong sena, re tla hlahloba thepa le melemo ea HEMC le ts'ebeliso ea eona indastering ea kaho.

Thepa ea HEMC

HEMC ke phofo e tšoeu kapa e bosoeu e sa nkheng le e sa latsoeheng. E qhibiliha ka metsing a batang 'me e etsa tharollo e hlakileng kapa e fokolang. The viscosity ea tharollo e itšetlehile ka mahloriso a HEMC le tekanyo ea substitution (DS), e leng karolelano ea palo ea lihlopha tsa hydroxyl tse nkeloang sebaka ke lihlopha tsa methyl le hydroxyethyl ho palo eohle ea lihlopha tsa hydroxyl ka molek'hule ea cellulose.

HEMC e na le thepa e 'maloa e lakatsehang e e etsang tlatsetso e loketseng thepa ea kaho:

  1. Ho boloka metsi: HEMC e ka monya metsi le ho e tšoara ka har'a motsoako, e fokotsa bongata ba metsi a hlokahalang le ho thibela ho fokotseha le ho phunyeha.
  2. Thickening: HEMC e eketsa viscosity ea motsoako, ho ntlafatsa ts'ebetso le ho thibela ho arohana.
  3. Tlamahano: HEMC e sebetsa e le tlamahano, e tšoara motsoako hammoho le ho ntlafatsa ho khomarela holimo.
  4. Sebopeho sa filimi: HEMC e ka etsa filimi e tšesaane holim'a metsi, e ntlafatsa ho hanyetsa metsi le ho tšoarella.

Likopo tsa HEMC ho Kaho

HEMC e sebelisoa haholo indastering ea kaho e le tlatsetso linthong tse fapaneng. Tse ling tsa lisebelisoa tsa eona tse tloaelehileng li kenyelletsa:

  1. Seretse: HEMC e kenngoa seretseng ho ntlafatsa ts'ebetso, ho fokotsa tlhokahalo ea metsi, le ho eketsa ho boloka metsi. E boetse e ntlafatsa matla a tlamahano le ho tšoarella ha seretse.
  2. Li-Adhesives tsa Lithaele: HEMC e sebelisoa ho li-adhesives tsa lithaele ho ntlafatsa ho kolobisa le ho fokotsa ho thella, ho ntlafatsa ho khomarela le ho tšoarella ha lithaele.
  3. Grouts: HEMC e eketsoa ho li-grouts ho ntlafatsa ts'ebetso, ho fokotsa ho fokotseha le ho phunyeha, le ho matlafatsa ho thibela metsi.
  4. Stucco le Plaster: HEMC e sebelisoa ka sekoti le samente ho ntlafatsa ts'ebetso, ho fokotsa ho petsoha, le ho eketsa ho boloka metsi. E boetse e ntlafatsa matla a ho kopanya le ho tšoarella ha thepa.
  5. Metsoako ea ho ikemela: HEMC e eketsoa ho metsoako ea ho ikemela ho ntlafatsa phallo le ho leka-lekanya, ho fokotsa ho fokotseha le ho phunyeha, le ho matlafatsa ho thibela metsi.

Melemo ea HEMC ka Kaho

HEMC e fana ka melemo e mengata ho thepa ea kaho, ho kenyelletsa:

  1. Mosebetsi o ntlafetseng: HEMC e ntlafatsa ho sebetsa ha thepa, ho etsa hore ho be bonolo ho sebetsana le ho sebelisoa.
  2. Tlhokahalo e fokotsehileng ea metsi: HEMC e fokotsa bongata ba metsi a hlokahalang motsoakong, ho ntlafatsa matla le ho tšoarella ha thepa.
  3. Ho boloka metsi a eketsehileng: HEMC e ntlafatsa ho boloka metsi a thepa, ho thibela ho fokotseha le ho phunyeha le ho matlafatsa nako e telele ea tsona.
  4. Ho khomarela ho matlafalitsoeng: HEMC e ntlafatsa ho khomarela lisebelisoa holim'a metsi, ho matlafatsa nako le matla a tsona.
  5. Ho ntlafala ho hanyetsa metsi: HEMC e etsa filimi e tšesaane holim'a metsi, e ntlafatsa ho thibela metsi le ho tšoarella ha bona.

Qetello

HEMC ke kompone e nang le mefuta e mengata e fanang ka melemo e mengata indastering ea kaho. Mehaho ea eona e ikhethang e etsa hore e be sehlahisoa se loketseng linthong tse fapaneng tse kang seretse, li-grouts le samente. Ka ho ntlafatsa bokhoni ba ho sebetsa, ho fokotsa tlhokahalo ea metsi, le ho matlafatsa ho boloka metsi le ho khomarela, HEMC e ntlafatsa matla, ho tšoarella, le ts'ebetso ea kaho.
