1. Tuhinga o mua o te cellulose eter
Ko te Cellulose Ether mo te hanga ko te polymer wai-kore-inoic-kore e puta ana:
Ko te Celllose (he penupenu rakau, he koti ranei)
HPMC-hydroxypropyl methyl cellulose eter
Hec-hydroxyethyl cellulose eter
Hemc-hydroxyethyl methyl cellulose eter
Efec-ethyl hydroxyethyl cellulose eter
Mc-methyl cellulose Ether
2. Nga ahuatanga o te Eter Cellulose
Ko nga ahuatanga o te Cellulose Ethers i runga i:
Ko te tohu o te polymerization DP te maha o nga waeine-a-waho-tirohanga
Ngaro me te tohu o te whakakapinga, te tohu o te whakakotahitanga o te whakakapi - Whakatauhia te mara tono
Rahi matūriki - te whakaheke
Maimoatanga mata (ara, kua oti te whakakorekore) - ko te waa tirotiro he hononga ki te uara pH o te punaha
Tohu Whakawa - Whakapaihia te Taonga Taonga me te Mahi o te Eter Cellulose.
3. Te mahi o te Eter Cellulose - Te Whakapono Watea
Ko te Cellulose Ether he kohinga mekameka a Polymer i hangaia e nga waahanga β-D-Glucose. Ko te roopu hydroxyl i roto i te ngota me te ngota hāora i runga i te hanga ngota o te waikawa me te wai ngota wai i runga i te mata o te mekameka polymer me te akiaki i nga ngota. I roto i te mekameka, ka whakakorea te whakaetonga i te wai ka uru ki te paparanga turanga.
He painga e whakaratohia ana e nga momo pupuri i te wai o te Cellulose Ethes:
Kaore he hiahia ki te horoi i te paparanga turanga, te whakaora
hanga pai
He Kaha Rawa
4
Ka taea e te Ether Celllose te whakapiki i te kotahitanga i waenga i nga waahanga o te paru-a-Gypsum, e whakaatuhia ana i roto i te pikinga o te riterite o te paru.
Ko nga painga matua e whakaratohia ana e te matotoru o te cellulose Heahe:
Whakaitihia te pungarehu whenua
Whakanuia te whakapiki i te turanga
Whakaitihia te arai o te paru
Kia mau tonu te paru
5. Te mahi o te Eter Cellulose - Ngohe Mata
Kei roto i a Celllose Ether nga roopu hydrophilic (nga roopu hydroxyl, nga roopu hydrophobic (nga roopu methyl (nga roopu athyl, te mowhiti.
(Ko te kaha o te mata o te wai ko te 72mn / m, ko te 4mn / m, me te cellulose Ether ko te HPC 42, te HPMC 50, MC 69, CMC 79, CMC 79, CMC 79, CMC 79, CMC 79, CMC 79, CMC 79, CMC 79, CMC 79, CMC 79, CMC 79, CMC 79, CMC 79, CMC 79, CMC 79, CMC 79, CMC 79, CMC 79, CMC 79
Ko nga painga matua e whakaratohia ana e te mahinga o te mata o te cellulose Heahe:
Te kaha o te hau (he maeneene maeneene, he iti te roa o te paru, te whakaheke i te whakaheke i te aukati, te aukati koreutu-thaw)
Maroke (ka piki ake te whakapiri ki te tihi)
6. Nga whakaritenga o te raima raima rama mo te cellulose eter
(1). Te pupuri i te wai
(2). Te mahi pai, kaore he kaihoroi
(3). He maeneene te panui
(4). Te kaha anti-sabing
(5). He teitei ake te pāmahana o te tipu i te 75 ° C
(6). Te Whakatau Tere Tere
(7). He pai ake te kaha ki te whakauru i te hau me te whakanui i nga mirumiru hau i roto i te paru
11. Me pehea te whakatau i te horopeta o te Eter Cellulose
Mo nga papa raima, he mea tika kia mau tonu te wai i roto i te mokete mo te waa roa kia pai ai te mahi me te karo i nga kapiti. I te wa ano, ka mau tonu te whakamahi cellulose i te nui o te wai e tika ana mo te wa roa kia pai ai te mokete.
Ko te nui o te cellulose Ether e whakawhirinaki ana ki:
Te tirohanga o te Ether Cellulose
Te mahinga whakaputa o te cellulose eter
Ihirangi whakakapinga me te tohatoha o te eter cellulose
Te tohatoha rahi matūriki o te eter cellulose
Nga momo me te whakahiato o te paru-a-miihini
Te kaha o te wai o te paparanga turanga
Te kohi wai mo te rereketanga o te paerewa o te paru-a Gypsum
Te whakarite i te wa o te raima gypsum
Te matotoru hanga me te mahinga hanga
Nga tikanga hanga (penei i te pāmahana, te tere o te hau, me etahi atu)
Tikanga hanga (te tuhi ā-ringa, te rehu miihini)
