Putty powder ndi zida zomangira zodziwika bwino zomwe zimagwiritsidwa ntchito kudzaza mipata, ming'alu ndi mabowo pamalo opaka utoto kapena matayala. Zosakaniza zake zimapangidwa ndi gypsum powder, talcum powder, madzi ndi zipangizo zina. Komabe, ma putty opangidwa amakono alinso ndi chowonjezera, hydroxypropyl methylcellulose (HPMC). Nkhaniyi ifotokoza chifukwa chake timawonjezera HPMC ku ufa wa putty ndi zabwino zomwe zimabweretsa.
Hydroxypropyl methylcellulose ndi polima wosungunuka m'madzi wochokera ku cellulose, chigawo chachikulu cha makoma a cellulose. Amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana monga zomangamanga, zamankhwala, nsalu ndi chakudya. Pomanga, amagwiritsidwa ntchito ngati chophatikizira mumatope, grouts, utoto ndi putty.
Kuwonjezera HPMC ku putty powder kuli ndi ubwino wotsatira:
1. Wonjezerani kusunga madzi
HPMC ndi hydrophilic polima kuti zimatenga ndi kusunga mamolekyu madzi. Kuonjezera HPMC ku ufa wa putty kumatha kupititsa patsogolo ntchito yake yosungira madzi. Panthawi yomanga, ufa wa putty wosakanikirana ndi HPMC sudzauma mofulumira, kupereka antchito nthawi yokwanira yogwiritsira ntchito zinthuzo ndikudzaza bwino mipata popanda kuchititsa kuti zinthuzo ziwonongeke kapena kuchepa. Pamodzi ndi kuchuluka kwa kusungirako madzi, ma putty powders amalumikizana bwino ndi malo, kuchepetsa mwayi wosweka kapena kusenda.
2. Kupititsa patsogolo ntchito
Ufa wa putty umasakanikirana ndi HPMC kuti ukhale wofanana ndi phala, kupangitsa kuti ikhale yosavuta kugwiritsa ntchito ndikufalikira ponseponse. HPMC imapatsa ma putty powders mawonekedwe osalala, operekera kutha kwabwinoko popaka penti kapena matayala. Zimapatsanso putty mtengo wochuluka wokolola, kuthekera kokana kusinthika mopanikizika. Izi zikutanthauza kuti ufa wa putty wosakanikirana ndi HPMC ukhoza kupangidwa mosavuta ndikuwumbidwa kuti ugwirizane ndi malo osiyanasiyana.
3. Chepetsani kuchepa ndi kusweka
Monga tanenera kale, HPMC ikhoza kukonza kusungirako madzi kwa putty powder. Chotsatira chake, ufa wa putty sungathe kuuma mofulumira kwambiri ukagwiritsidwa ntchito pamwamba, kuchititsa kuchepa ndi kusweka. HPMC imathandizanso kuchepetsa kuchepa ndi kusweka chifukwa kumawonjezera mphamvu ya mgwirizano wa ufa wa putty, zomwe zimapangitsa kuti zinthuzo zikhale zokhazikika komanso zosavuta kusweka.
4. Kukana bwino kwa madzi ndi kusintha kwa kutentha
Putty ufa wosakanizidwa ndi HPMC uli ndi kukana bwino kwa madzi ndi kusintha kwa kutentha kusiyana ndi putty ufa wopanda HPMC. HPMC ndi hydrophilic polima kuti amateteza putty ufa ku kutentha ndi kusintha chinyezi. Izi zikutanthauza kuti ufa wa putty wosakanizidwa ndi HPMC ndi wokhazikika ndipo umatha kupirira kukhudzana ndi nyengo zosiyanasiyana.
5. Utali wa alumali moyo
Kuonjezera HPMC ku ufa wa putty kumatha kutalikitsa moyo wake wa alumali. HPMC imalepheretsa ufa wa putty kuti uume ndi kuumitsa panthawi yosungira. Izi zikutanthauza ufa wa putty wosakanikirana ndi HPMC ukhoza kusungidwa motalika popanda kutaya khalidwe kapena kukhala wosagwiritsidwa ntchito.
Pomaliza, kuwonjezera HPMC ku putty powder kuli ndi zabwino zingapo. Imawonjezera kusungirako madzi, imapangitsa kusinthika, imachepetsa kuchepa ndi kusweka, imapereka kukana bwino kwa madzi ndi kusintha kwa kutentha, ndikuwonjezera moyo wa alumali. Ubwino wonsewu umatsimikizira kuti ufa wa putty wosakanikirana ndi HPMC upereka kumaliza kwabwinoko komanso kukhala kolimba. Motero, ndi chinthu chofunika kwambiri chimene chimathandiza kuti ntchito yomanga iliyonse ipambane.
Ponseponse, kugwiritsa ntchito HPMC mu ufa wa putty ndi chitukuko chabwino chamakampani omanga. Limapereka maubwino ambiri omwe amathandiza kuti ntchito ya aliyense ikhale yosavuta, yogwira mtima komanso yothandiza. Kugwiritsiridwa ntchito kwake kosalekeza kungapangitse kuti pakhale zina zatsopano zomwe zingapangitse kuti zipangizo zomangira ndi zomangamanga zikhale bwino.
