Pakadali pano, mtundu wa nyumba ya Hydroxpyl wa methylcellulose umasiyana kwambiri, ndipo mtengo umasiyanasiyana kwambiri, ndikupangitsa kukhala kovuta, kumapangitsa kuti zikhale zovuta kwa makasitomala kuti asankhe bwino. HPMC yosinthidwa kampani yomwe inasinthidwanso ndi zotsatira za zaka zambiri. Kuphatikiza kwa zinthu zamayendedwe kumatha kusintha magwiridwe antchito ndikuwongolera kubizinesi. Inde, zimakhudza zina, koma nthawi zambiri zimalankhula bwino. Cholinga chowonjezera chowonjezera ndi kuchepetsa mtengo, zomwe zimapangitsa kuti zisungunuke bwino madzi, zokhala ndi zovuta zina, zomwe zimayambitsa mavuto ambiri.
Pali kutsata kusiyana pakati pa HPMC ndi kusinthika HPMC:
1. HPMC yosinthika imakhala ndi madzi abwino ndipo imamva kulemera, yomwe ndi yosiyana ndi yosiyanasiyana yofananira.
2. Kuchita zachiwerewere HPMC Aquaous yankho ndi mitambo, ndipo ndalama zosunga madzi ndizovuta kufikira 80%.
3. Oyera HPMC sayenera kununkhiza ammonia, wowuma ndi mowa; HPMC yoyesedwa imatha kununkhiza mitundu yonse ya fungo lambiri, ngakhale zitakhala zopweteka, zimamveka bwino.
4. HPMC yoyesedwa imatha kuonedwa ngati granolar imakhazikika kapena makristals pansi pa ma microscope kapena galasi.
Kutalika kopitilira 200,000?
Akatswiri ambiri apakhomo ndi akatswiri afalitsa mapepala omwe amakhulupirira kuti kupanga kwa HPMC kumangolekeredwa ndi zitseko zapakhomo ndi kusindikiza kochepa, ndipo mabizinesi wamba sangathe kupanga zinthu zoposa 200,000. M'chilimwe, ndizosatheka kupanga zinthu zomwe zimakufanizira zoposa 80,000. Amakhulupirira kuti otchedwa 200,000 ayenera kukhala zinthu zabodza.
Kukangana kwa katswiri sikutanthauza. Malinga ndi zomwe zinali pabanja lam'nyumba, zomwe zili pamwambapa zitha kujambulidwa.
Chinsinsi chowonjezera mawonekedwe a HPMC ndi kusindikizidwa kwakukulu kwa riyakitala komanso zokhudzana ndi zomwe zimachitika komanso zida zapamwamba kwambiri. Wogwiritsa ntchito kwambiri amalepheretsa kuwonongeka kwa cellulose mwa okosijeni, ndipo othamanga kwambiri amalimbikitsa kulowa kwa wothandizila ku cellulose ndikuwonetsetsa kuti mafanowo.
Mlozera woyambirira wa 200000cps hydroxypylth methylcellulose:
2% ya madzi am'madzi aku Isccen 200000cps
Kuyera kwa Zogulitsa ≥98%
Methoxy Zokhudza 19-24%
Ma hydroxypropoxy: 4-12%
200000cps hydroxypypyl methylcellulose:
1. Kusunga kwamadzi koyenera komanso katundu wambiri kuti mutsimikizire kukoma mtima kwa slurry.
2. Mphamvu yayikulu ndi mphamvu yofunika kwambiri ya mpweya, mwamphamvu imaletsa kuchita manyazi komanso kusokonekera.
3. Chepetsa kutentha kwa simenti hydration, kuchedwetsa kulowa nthawi, ndikuwongolera nthawi yodziwika bwino ya simenti.
4. Sinthani madzi osasinthika a matope, sinthani chinsinsi, ndipo pewani tsankho komanso magazi.
5. Zogulitsa zapadera, tikufuna kutentha kwabwino kwambiri nthawi yachilimwe, kuti tiwonetsetse bwino zamagetsi osamuchepetsa.
Chifukwa cha kuyang'anira kwa msika wa lax, mpikisano mu makampani opanga matoma akukulirakulira. Pofuna kuteteza pamsika, ogulitsa ena adasakanikirana ndi zinthu zambiri zopangira mitengo yotsika mtengo kuti apange ma etherse. Apa, mkonziyo amakakamizidwa kuti akumbutse makasitomala osakhala ndi mitengo yotsika, kuti musapusitsidwe anyengedwe, zimayambitsa ngozi, ndipo pamapeto pake titataya ndalamazo.
Njira zodziwika bwino komanso njira zodziwitsira:
.
Njira Yodziwitsa: Chifukwa cha mawonekedwe a amisiri, mtundu wamtunduwu nthawi zambiri umakhala ndi chingwe cholumikizira, koma cellulose ense sawoneka cholembera chitatha, chofunda chili ngati chomangira koma chosalumikizidwa.
(2) Onjezani wowuma kupita ku cellulose ether. Wowuma nthawi zambiri amasuka m'madzi, ndipo yankho nthawi zambiri amakhala ndi kuwala kochokera.
Njira Yodziwitsa: Drowel cellulose yankho ndi ayodini, ngati mtunduwo usanduka wabuluu, ukhoza kuonedwa kuti wowuma wawonjezeredwa.
(3) Onjezani polyvinyl mowa. Monga tonse tikudziwa, msika wamsika wa polyvinyl mowa ufa wa 2488 ndipo 1788 nthawi zambiri amakhala otsika kuposa a cellulose, ndikusakaniza polyvinyl mowa umatha kuchepetsa mtengo wa etheluse ether ether.
Njira yodziwitsa: Mtundu wamtunduwu nthawi zambiri umakhala wonyezimira komanso wawuma. Imasungunuka mwachangu ndi madzi, sankhani yankho ndi ndodo yagalasi, padzakhala zigawo zowonekeratu.
Chidule: Chifukwa cha kapangidwe kake ndi magulu, kusungira kwamadzi kwa ethel ether sikungasinthidwe ndi zinthu zina. Ziribe kanthu mtundu wanji wafeser umasakanikirana, bola zitasakanikirana kwambiri, kusunga madzi kumachepetsedwa kwambiri. Kuchuluka kwa hpmc ndi mamasukidwe abwinobwino kwa 10w mu matope wamba ndi 0.15 ~ 0.2 ‰, ndipo malo osungira madzi ali> 88%. Magazi amakhala ovuta kwambiri. Chifukwa chake, kuchuluka kwa madzi ndi chizindikiro choyenera kuyeza mtundu wa hpmc, kaya ndikwabwino kapena koyipa, bola zimawonjezedwa ndi matope, zimawonekera pang'ono.
