Kumanga vuto la guluu - hydroxypropyl methyl cellulose

Chiyambi:
M'malo omanga ndi zomangamanga, zomatira zimakonda kugwira ntchito yofunika kwambiri. Mwa awa, hydroxypropyl methy cellose (hpmc) imawoneka ngati yolimba komanso yogwiritsidwa ntchito kwambiri mu mawonekedwe osiyanasiyana omatira. Kumvetsetsa komwe kumakhala kwake, kugwiritsa ntchito, komanso zovuta zokhudzana ndi kugwiritsa ntchito kwake popanga maulalo okhala ndi kofunikira kuti mukwaniritse makina okhazikika komanso opirira.

Ndi chiyaniHydroxypyl noth cellose (hpmc)?
Hydroxypyl methl cellulose, yomwe imadziwika kuti Hopmc, ndi polymer yopanda madzi yosungunuka yochokera ku cellulose. Imapangidwa kudzera mu kusintha kwa mankhwala kwa cellulose, polysacchabide mwachilengedwe opezeka m'makoma a cell a mbewu. Kusintha kumaphatikizapo kuyambitsa kwa hydroxypyl ndi methyl magulu am'deralo a cellulose, chifukwa chophatikizika ndi zida zapadera pazoyenera kugwiritsa ntchito ntchito zosiyanasiyana.

Katundu ndi mawonekedwe a HPMC:

Kusungunuka kwamadzi: chimodzi mwazomwe zimatanthauzira kwa HPMC ndi kukhazikika kwa madzi ambiri. Akasakanizidwa ndi madzi, hpmc amapanga chomveka bwino, ma viscous yankho, kupangitsa kuti ikhale yosavuta kuphatikiza mapangidwe ake monga atsogoleri.
Kutha kwa makanema: hpmc kumakhala ndi mafilimu osinthika komanso ogwirizana atayanika. Katunduyu ndi wopindulitsa kwambiri mu zomatira, pomwe mgwirizano wolimba ndi wofowonera umafunidwa.
Zotsatira ndi Coute: HPMC imawonetsa zonse zomatira komanso zophimba, zomwe zimawathandiza kutsatira magawo osiyanasiyana pomwe akusunga mphamvu zamkati mkati mwa chomatira.
Kuwongolera kwa Rhelogical: HPMC kumagwira ntchito ngati rheology yosintha motsatira mapangidwe, kukhudzika kwa mapangidwe, mayendedwe oyenda, ndi thixotropy. Izi zimathandiza kuti azilamulira pazinthu zogwiritsira ntchito ndipo zimawonetsetsa kuti pomanga panthawi yomanga.
Mapulogalamu a HPMC pakupanga guluu:
HPMC imapeza kugwiritsa ntchito makampani omanga, makamaka pakupanga zomata zamitundu yosiyanasiyana:

Zilonda za Tile:Hpmcndi gawo lofunikira mu zomata za tile, komwe limakhala ngati chofunda, chomatira pakati pa matailosi ndi magawo a tiles. Katundu wake wamakanema amathandizira kupanga mapangidwe owoneka bwino omwe amatha kukhala ndi zipsinjo zapadera ndi zinthu zachilengedwe.
Malonda a simenti ndi ma punyani: Mu simenti ndi ma pusterters, ntchito za HPMC ngati othandizira kukula ndi ntchito yosungirako madzi. Zimathandizira kugwirira ntchito, kumathandizira kutsatira magawo, ndipo imalepheretsa kusaka kapena kuwonongeka pakugwiritsa ntchito ndi kuyanika.
Kuphatikiza kolunjika ndi zolumikizira: mankhwala ophatikizika a hpmc ndi zigawo zosindikiza amagwiritsidwa ntchito podzaza mipata, ming'alu, ndi mafupa pomanga. Mapangidwe awa amapatsa zabwino kwambiri, kusinthasintha, ndi kukhazikika, kuwonetsetsa zisindikizo zamuyaya ndikumaliza.
Zochita zabodza: ​​Kutuma kwa kunja ndi matembenuzidwe omaliza (mawu) kudalirabe zomatira HPMC-yokhala ndi zomatira zolumikizira zibodi zakunja. Chotsanga chomatira chimayenera kugwiritsidwanso ntchito moyenera komanso mosagwirizana kuti muwonetsetse kuti zisumbu komanso zanyengo.
Zovuta pakupanga guluu ndi HPMC:
Ngakhale anali mapindu ake ambiri, kugwiritsa ntchito HPMC pakupanga gulu laudindo kumatha kubweretsa zovuta zina:

Kugwirizana ndi zowonjezera zina: Kupanga zinthu zomatira zomatira nthawi zambiri kumaphatikizapo kuphatikiza kwa zowonjezera zosiyanasiyana monga ma mafilimu, mateletse, ndi osabala. Kukwaniritsa kulingana pakati pa HPMC ndi zowonjezera izi ndikofunikira kuti musunge magwiridwe antchito ndi kusasinthika.
Kuyanika nthawi ndi kuchiritsa mtengo: nthawi yopuma ndi kuchiritsa machenjerero a HPMC Kukhazikitsa Kwambiri ndi Kuwongolera kwa magawo awa ndikofunikira kuti mupewe kuyanika musanayime kapena kukongoletsa kokwanira, zomwe zingasokoneze mphamvu.
Mphamvu yakulimba ndi kukhazikika: Pomwe HPMC imapereka chitsamba chabwino kwambiri komanso chiphunzitso chomatira, kukwaniritsa mphamvu yabwino ndi kulimba kwamphamvu. Kulumikizana kosakwanira kumatha kudzetsa kumeta, kugwedeza, kapena kulephera pansi pa katundu.
Maganizo a chilengedwe: Zochita za HPMC zochokera kuwonongeka ndikuwonongeka pakuwononga zachilengedwe monga chinyezi chambiri, kutentha kwambiri, kapena kuwonekera pa radiation ya UV. Kusankhidwa koyenera kwa HPMC kwa HPMC ndi zowonjezera zowonjezera kumatha kuchepetsa zotsatirazi ndi kupitiriza kuchita.

Hydroxypropyl methyl cellulose (hpmc)Imagwira ntchito yofunika kwambiri yopangira guluu, ndikupereka mphamvu yolimbika, kusinthasintha, komanso kugwira ntchito pomanga ntchito. Mwa kumvetsetsa katundu ndi zovuta zomwe zimakhudzana ndi zomata za HPMC zokhudzana ndi HPMC, zomangamanga ndi opanga zimatha kuyesetsa kukonza njira, ndikuwonetsetsa kuti nditakhala kuti nditakhala moyo wambiri wopangidwa. Popitiliza kufufuza ndi kusankhananso, HPMC imakhalabe yofunika kwambiri m'zida zomanga, zomwe zimathandizira kuti zikhazikike ndi malo okhazikika komanso okhazikika.
