1. Kuyamba
Hydroxypypyl methylcellulose (hpmc) ndi cellulose eyelil ogwiritsidwa ntchito kwambiri pomanga zida zomangira. Pogwiritsa ntchito ufa wa putty, hpmc amachita gawo lofunikira kwambiri m'chitsacho ndi kusungidwa kwamadzi, zomwe zimakhudzanso ntchito yomangayi ndikugwiritsa ntchito ufa wa punty.
2. Makhalidwe oyambira a HPMC
HPMC ndi ma cellulose osakhala ethee ether ether adalandira ndi kusintha kwa mankhwala a cellulose yachilengedwe. Magulu a methoxyproxy ndi hydroxyprophoxy amayambitsidwa mu mawonekedwe ake, omwe amapangitsa HPMC kukhala ndi madzi abwino ndikupanga mafilimu. Kuphatikiza apo, hpmc imakhalanso ndi bata kwambiri komanso kukana kwa enzymatic hydrolysis, yomwe imapangitsa kuti ikhale yogwiritsidwa ntchito kwambiri pakumanga.
3. Limagwirizanitsani kukulitsa chitsandikiro cha putty ufa
3.1 Zochitika Pamaso ndi Chida
HPMC ili ndi zochitika zabwino zapamwamba, zomwe zimatha kuchepetsa kusamvana pakati pa putty ufa ndi gawo lapansi ndikuwonjezera chitsiritso chazinthuzo. Pamene putty ufa umalumikizana ndi gawo la ma vanifolomu labwino kwambiri ndikulumikizani kwambiri kuti apange chofunda, potengera kutsatira ufa wa puety.
3.2 mawonekedwe opanga mafilimu
HPMC imatha kupanga njira yokhazikika ya colloidal mu njira yothetsera matenda am'madzi. Madzi akamatuluka, hpmc apanga filimu yolimba komanso yotanuka pamwamba. Kanemayu sangangowonjezera mgwirizano pakati pa ufa wa putty ndi gawo lapansi, komanso kuyikanso kupsinjika komwe kumachitika chifukwa cha kusintha kwa kutentha kapena kukhetsa pang'ono pang'onopang'ono.
3.3 Kukulunga Bridge Endost
HPMC imatha kukhala ngati balar mu punty ufa kuti apange mlatho wolumikizana. Mlatho wolumikizira uwu sunapangitse cholumikizira cha zigawozo mu ufa wa putty, komanso umasintha makina ogwiritsira ntchito makina pakati pa ufa wa putty ndi gawo lapansi. Moleklusi yayitali ya HPMC imatha kulowa mu pores kapena malo owuma a gawo lapansi, potero ndikulimbika kukulitsa chipilala cha ufa wa punty.
4. Makina osintha chitetezo chamadzi cha putty ufa
4.1 Kusungidwa kwamadzi ndikuchedwa kuyanika
HPMC ili ndi malo abwino osungirako madzi ndipo amatha kuchedwetsa madziwo m'madzi mu ufa. Katunduyu ndi wofunikira makamaka pa ntchito yomanga, chifukwa datty ufa umafunika madzi okwanira ma hydrate ady informaction njira yowuma. HPMC imatha kusunga madzi, kotero ufa uwu ukhoza kukhalabe wosasinthika wochita masewera olimbitsa thupi kwa nthawi yayitali, potero ndikupititsa patsogolo ntchito yomanga ndikupewa kusokonekera chifukwa chayanika chifukwa choyanika mwachangu kwambiri.
4.2 Kuchulukitsa kufanana kwa magawidwe amadzi
Mapangidwe a ma mesh opangidwa ndi hpmc mu ufa putty ufa umatha kugawa madzi ndikupewa vuto la madzi ochulukirapo kapena osakwanira. Kugawa kwamadzi kumeneku sikungothandiza kubizinesi ya putty
4.3 Kuwongolera chinyezi
HPMC imasintha chinyezi cha ufa wa putty potenga ndi kumasula madzi, kuti ithe kukhala kunyowa kwabwino kwambiri kunyowa ndi kunyowa kwamphamvu. Kusungidwa kwanyoka sikungotengera nthawi yotseguka ya putty
5. Zolemba
Muzinthu zenizeni, kuchuluka kwa hpmc mu punty ufa nthawi zambiri pakati pa 0,1% ndi 0,5%, ndipo kukhazikika kwina kumadalira mawonekedwe a ufa ndi zofuna zomanga. Mwachitsanzo, mukamamanga kutentha kwakukulu kapena malo owuma, kuchuluka kwa HPMC kungawonjezeredwe moyenera kuti athandize kukonza madzi osavomerezeka komanso othamangitsa a purty. Komabe, nthawi zina pomwe kutsatira kwapamwamba kumafunikira, kugwirira ntchito kwa putty ufa kumatha kukunjezaninso pakuwonjezera zomwe zili mu HPMC.
Kugwiritsa ntchito rpmc mu punty ufa kumapangitsa chidwi chake chatsanzi ndi kusungidwa kwamadzi. Zina mwazowonjezera zimatheka kudzera pazinthu, zomwe zimapangidwa ndi mafilimu, kulumikizana ndi Bridge zotsatira za HPMC, ndipo kusungidwa kwamadzi, kuchedwa kupukuta ndi kunyowa Kuuma ndi kunyowa. Kuyambitsa kwa HPMC sikungosintha magwiridwe antchito a putty, komanso kumathandizanso kuti pakhale bwino pomanga zida zodzikongoletsera zodzikongoletsera zodzikongoletsera.
