Popanga ufa wa putty, kuwonjezera kuchuluka koyenera of Hydroxypropyl Methyl Cellulose (HPMC)ikhoza kupititsa patsogolo ntchito yake, monga kukonzanso rheology ya putty powder, kukulitsa nthawi yomanga, ndi kuwonjezera kumamatira. HPMC ndi thickener wamba ndi zosintha, chimagwiritsidwa ntchito zomangira, zokutira, zomatira ndi zina. Pa ufa wa putty, kuwonjezera HPMC sikungangopititsa patsogolo ntchito yomanga, komanso kumapangitsanso kudzaza mphamvu ndi anti-cracking performance ya putty.

 

Udindo wa hydroxypropyl methylcellulose
Kupititsa patsogolo kayendedwe ka madzi ndi ntchito yomanga: HPMC imakhala ndi mphamvu yowonjezera yowonjezera, yomwe imatha kupititsa patsogolo kusungunuka kwa ufa wa putty, kupangitsa kuti ufa wa putty ukhale wofanana kwambiri komanso wosatheka kutuluka pamene ukugwiritsidwa ntchito ndi kukonzedwa, komanso kupititsa patsogolo ntchito ndi zomangamanga.

 

Kupititsa patsogolo kumamatira: Kuphatikizika kwa HPMC kumatha kupititsa patsogolo kumamatira pakati pa ufa wa putty ndi zinthu zoyambira, kupewa mavuto monga putty powder kugwa ndi kusweka.

 

Kupititsa patsogolo kusungirako madzi: HPMC ikhoza kuonjezera kusunga madzi kwa ufa wa putty, kuchepetsa kutentha kwa madzi, potero kuteteza putty kuti asawume ndi kusweka, ndikuthandizira putty kuti ikhale yofanana panthawi yowumitsa.

 

Kupititsa patsogolo kukana kwa ming'alu: Mapangidwe a polima a HPMC amatha kusintha kusinthasintha kwa ufa wa putty ndi kuchepetsa ming'alu yomwe imayambitsidwa ndi kusweka, kusintha kwa kutentha kapena kusinthika kwa maziko.

 

Kuchuluka kwa Hydroxypropyl Methylcellulose Kuwonjezedwa
Nthawi zambiri, kuchuluka kwa hydroxypropyl methylcellulose komwe kumawonjezeredwa nthawi zambiri kumakhala pakati pa 0.3% ndi 1.5% ya kulemera konse kwa ufa wa putty, malingana ndi mtundu wa ufa wa putty womwe umagwiritsidwa ntchito, ntchito yofunikira, ndi zofunikira pakugwiritsa ntchito.

 

Low viscosity putty powder: Pazinthu zina za putty zomwe zimafuna madzi abwino, HPMC yowonjezera yowonjezera ingagwiritsidwe ntchito, kawirikawiri pafupifupi 0.3% -0.5%. Cholinga cha mtundu uwu wa putty ufa ndikupititsa patsogolo ntchito yomanga ndikuwonjezera nthawi yotseguka. Kuchuluka kwa HPMC kungapangitse ufa wa putty kukhala wowoneka bwino komanso kukhudza zomangamanga.

 

Kuchuluka kwa viscosity putty powder: Ngati cholinga chake ndi kupititsa patsogolo kumamatira ndi kukana ming'alu ya putty, kapena makoma omwe ali ndi chithandizo chovuta chapansi (monga malo okhala ndi chinyezi chambiri), kuchuluka kwapamwamba kwa HPMC kungagwiritsidwe ntchito, kawirikawiri 0.8% -1.5%. Cholinga cha ma putty powders awa ndikuwongolera kumamatira, kukana ming'alu ndi kusunga madzi.

 

Maziko osinthira kuchuluka kwa kuwonjezera
Malo ogwiritsira ntchito: Ngati malo omangira ali ndi chinyezi chambiri kapena kutentha kochepa, kuchuluka kwa HPMC komwe kumawonjezeredwa nthawi zambiri kumawonjezeka kuti kusungidwe kwamadzi ndi ntchito yolimbana ndi kukwapula kwa putty powder.
Mtundu wa Putty: Mitundu yosiyanasiyana ya ufa wa putty (monga mkati mwa khoma putty, kunja kwa khoma putty, faini putty, coarse putty, etc.) ali ndi zofunika zosiyanasiyana HPMC. Fine putty imafuna kukhuthala kwambiri, kotero kuchuluka kwa HPMC komwe kumagwiritsidwa ntchito kudzakhala kokwera; pomwe kwa coarse putty, ndalama zomwe zawonjezeredwa zitha kukhala zochepa.
Mkhalidwe Woyambira: Ngati mazikowo ndi ovuta kapena ali ndi madzi amphamvu, pangakhale kofunikira kuonjezera kuchuluka kwa HPMC kuonjezera kumamatira pakati pa putty ndi maziko.

 

Kusamala pogwiritsa ntchito HPMC

Pewani kuwonjezera mopitirira muyeso: Ngakhale HPMC ikhoza kupititsa patsogolo ntchito ya ufa wa putty, HPMC yochuluka imapangitsa kuti ufa wa putty ukhale wovuta kwambiri komanso wovuta kumanga, komanso zimakhudzanso kuthamanga kwa kuyanika ndi kuuma komaliza. Choncho, kuchuluka kwa kuwonjezera kumafunika kuyendetsedwa molingana ndi zosowa zenizeni.

 

Kuphatikiza ndi zina zowonjezera: HPMC nthawi zambiri imagwiritsidwa ntchito pamodzi ndi zina zowonjezera monga mphira ufa, mapadi, etc. Ngati imagwiritsidwa ntchito pamodzi ndi zowonjezera zina kapena zosungira madzi, tcheru chiyenera kuperekedwa ku zotsatira za synergistic pakati pawo kuti apewe mikangano yogwira ntchito.

 

Kukhazikika kwazinthu:Mtengo wa HPMCndi chinthu chosungunuka m'madzi. Kuonjezera kwambiri kungapangitse kuti ufa wa putty utenge chinyezi ndikuwonongeka panthawi yosungira. Choncho, panthawi yopanga ndi kusungirako, kuchuluka kwa HPMC komwe kumagwiritsidwa ntchito kuyenera kuganiziridwa kuti zitsimikizire kukhazikika kwa ufa wa putty pansi pazikhalidwe zosungirako.

 

Kuonjezera HPMC ku ufa wa putty kumatha kupititsa patsogolo ntchito yake, makamaka pokhudzana ndi ntchito yomanga, kusunga madzi ndi kukana ming'alu. Kawirikawiri, kuchuluka kwa HPMC kuli pakati pa 0.3% ndi 1.5%, zomwe zimasinthidwa malinga ndi zosowa za mitundu yosiyanasiyana ya putty powder. Mukaigwiritsa ntchito, ndikofunikira kuwongolera kukulitsa kwake ndi zofunikira pakumanga kuti mupewe zotsatira zosafunikira zomwe zimachitika chifukwa chogwiritsa ntchito kwambiri.
