Pomanga khoma la putty, HPMC (hydroxypropyl methylcellulose) ndi chowonjezera chomwe chimagwiritsidwa ntchito nthawi zambiri chomwe chimatha kusintha kwambiri magwiridwe antchito a putty.
1. Sankhani mtundu woyenera wa HPMC
HPMC imapezeka mumitundu yosiyanasiyana yokhala ndi ma viscosities osiyanasiyana komanso kusungunuka kwamadzi. Posankha HPMC, mtundu woyenera uyenera kutsimikiziridwa kutengera mtundu wa putty ndi malo ogwiritsira ntchito. Nthawi zambiri, kukhuthala kochepa HPMC ndi oyenera putties kuti amafuna ntchito mwamsanga, pamene mkulu mamasukidwe akayendedwe HPMC ndi oyenera putties kuti amafuna nthawi yaitali lotseguka ndi adhesion wamphamvu.
2. Yang'anirani bwino mlingo
Kuchuluka kwa HPMC kumakhudza mwachindunji ntchito ya putty. Nthawi zambiri, kuchuluka kwa HPMC kumakhala pakati pa 0.5% ndi 2%, komwe kumasinthidwa molingana ndi mawonekedwe azinthu ndi zomangamanga. Kugwiritsa ntchito kwambiri HPMC kumatha kutalikitsa nthawi yowumitsa ya putty ndikusokoneza ntchito yomanga; pamene kugwiritsa ntchito kosakwanira kungakhudze kumamatira ndi kugwira ntchito kwa putty. Choncho, mlingo uyenera kulamulidwa mosamalitsa mu chilinganizo.
3. Kukonzekera koyenera
Pakukonzekera ndondomeko ya putty, tikulimbikitsidwa kuti tisungunuke HPMC m'madzi oyera kuti mupange yunifolomu yamadzimadzi ya colloidal, ndikusakaniza ndi zipangizo zina. Njirayi imatha kupewa kuphatikizika kwa HPMC ndikuwonetsetsa kubalalitsidwa kwake mu putty, motero kuwongolera magwiridwe antchito a putty.
4. Konzani malo omanga
HPMC amasonyeza katundu osiyana pansi kutentha ndi chinyezi zinthu. Nthawi zambiri, kutentha kwambiri ndi chinyezi kumathandizira kusungunuka ndi kuchitapo kanthu kwa HPMC. Chifukwa chake, pakumanga, kutentha koyenera ndi chinyezi cha chilengedwe kuyenera kusungidwa momwe mungathere kuti mukwaniritse ntchito yomanga ya putty.
5. Sinthani magwiridwe antchito a putty
HPMC akhoza kusintha kuterera ndi operability wa putty, kupanga kumanga bwino. Kuti apereke mwayi wonse pa izi, popanga putty, gawo la HPMC litha kuonjezeredwa moyenera kuti zitsimikizire kugwira ntchito kwabwino kwa putty panthawi yomanga ndikuchepetsa mphamvu ya ogwira ntchito yomanga.
6. Limbikitsani kumamatira kwa putty
Kuphatikizika kwa HPMC kumatha kusintha kwambiri kumamatira kwa putty, kulola kuti kumamatira bwino pamtunda komanso kuchepetsa chiopsezo cha peeling ndi kugwa. Pamaso kumanga, wosanjikiza m'munsi ayenera kuchitiridwa mokwanira kuonetsetsa kuti pamwamba ndi woyera ndi opanda madontho mafuta kukulitsa zotsatira adhesion wa HPMC.
7. Sinthani kukana kwa ming'alu
HPMC imatha kupititsa patsogolo kukana kwa putty, makamaka m'malo owuma komanso osintha kutentha. Posintha kuchuluka kwa HPMC, kusinthasintha ndi kukana kwa ming'alu kumatha kupitsidwanso pamlingo wina, potero kumakulitsa moyo wautumiki wa putty.
8. Chitani zoyeserera zoyenera
Asanamangidwe kwakukulu, tikulimbikitsidwa kuchita mayeso ang'onoang'ono kuti mutsimikizire kukhudzidwa kwa mitundu yosiyanasiyana ya HPMC pakuchita kwa putty. Kupyolera muzoyesera, chilinganizo choyenera chikhoza kupezeka kuti zitsimikizire mtundu wa zomangamanga.
9. Samalani ndi ndemanga za msika
Kufunika kwa msika kwa wall putty kumasinthasintha nthawi zonse, kotero ndikofunikiranso kulabadira ndemanga za ogula ndi zomwe akumana nazo. Kusintha kagwiritsidwe ntchito ka HPMC potengera mayankho amsika kumatha kukwaniritsa zosowa za ogwiritsa ntchito.
Kupyolera mu kusankha koyenera, kuwongolera molondola, kukhathamiritsa kwa ndondomeko, ndi chidwi ndi malo omanga, udindo wa HPMC mu khoma la putty ukhoza kugwiritsidwa ntchito mokwanira ndipo magwiridwe antchito ndi zomangamanga za putty zitha kuwongoleredwa. Pamene luso laukadaulo likupita patsogolo komanso kufunikira kwa msika, ndikofunikira kupitiliza kuphunzira ndikuwongolera njira zomangira. Ndikukhulupirira kuti malingaliro awa adzakuthandizani pakupanga khoma lanu la putty.
