Ma cellulose ethers ndi zinthu zomwe zimagwiritsidwa ntchito popanga utoto ndi zokutira monga putty powder. Putty ndi chodzaza ndi ufa chomwe chimagwiritsidwa ntchito kudzaza mipata, ming'alu ndi mabowo pamalo aliwonse. Cellulose ether imapangitsa kuti ufa wa putty ukhale wabwino popititsa patsogolo kumamatira kwake, kugwirizanitsa ndi zina zakuthupi. Posankha ma cellulose ethers a putty powder, njira zodzitetezera ziyenera kuchitidwa kuti zitsimikizire zotsatira zapamwamba.
Amapereka chitsogozo chokwanira pazinthu zomwe ziyenera kutsatiridwa posankha cellulose ether pa putty powder.
Chidziwitso #1: Dziwani mtundu wa ether wa cellulose wofunikira
Pali mitundu yosiyanasiyana ya ma cellulose ethers, kuphatikiza methylcellulose, ethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, ndi carboxymethylcellulose. Mtundu uliwonse wa ether wa cellulose uli ndi zinthu zapadera zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zina. Choncho, musanasankhe cellulose ether kwa putty ufa, m'pofunika kudziwa mtundu wa cellulose ether oyenera mtundu wa putty ufa.
Mwachitsanzo, hydroxyethyl cellulose (HEC) ndi yoyenera kugwiritsidwa ntchito mu putty powders chifukwa imapangitsa rheological katundu wa putty powder. HEC imakulitsa yankho, imalepheretsa kugwa, ndikuwonjezera kukhuthala kwa ufa wa putty. Methylcellulose, kumbali ina, si yoyenera kugwiritsidwa ntchito mu putty powder chifukwa ilibe katundu wofanana ndi HEC.
Chidziwitso #2: Dziwani kalasi ya cellulose ether yofunikira
Ma cellulose ethers amapezeka m'makalasi osiyanasiyana kutengera chiyero ndi kuyika kwake. Mtundu wa cellulose ether wofunikira pa putty ufa uyenera kutsimikiziridwa molingana ndi zofunikira za putty powder.
Magulu oyeretsedwa kwambiri a cellulose ethers amakondedwa kuposa ma cellulose ethers otsika chifukwa amaonetsetsa kuti ufa wa putty umagwira ntchito mosasinthasintha. Ether yoyera kwambiri ya cellulose ilibe phulusa, zotsalira ndi zonyansa zina zomwe zimakhudza ubwino wa putty powder.
Chidziwitso #3: Kuwunika Kusungunuka kwa Ma cellulose Ethers
Ma cellulose ethers amasungunuka m'madzi, koma kuchuluka kwa kusungunuka kumasiyanasiyana kutengera mtundu wa cellulose ether. Hydroxypropylcellulose (HPC) ndi chitsanzo cha cellulose ether yomwe ili yosasungunuka m'madzi; m'malo mwake, imabalalika mosavuta m'madzi.
Ndikofunikira kudziwa kusungunuka kwa cellulose ether yomwe imagwiritsidwa ntchito mu putty powder kuti iwonetsetse kuti imasungunuka mosavuta m'madzi ndipo sichimayambitsa kuphwanya kapena kusagwirizana mu putty powder.
Chidziwitso #4: Ganizirani Kutentha kwa Ntchito
Kutentha kwa zomangamanga kwa putty powder cellulose ether ndikofunikanso kulingalira. Mtundu uliwonse wa cellulose ether uli ndi kutentha kwapadera komwe umagwira ntchito bwino. Chifukwa chake, ndikofunikira kusankha ma cellulose ethers omwe amatha kupirira kutentha kwa kapangidwe ka putty powder.
Cellulose ether ili ndi kukhazikika kwabwino kwa kutentha ndipo ndi yoyenera kugwiritsidwa ntchito mu putty powder chifukwa sichidzasokoneza kapena kulephera kutentha kwambiri. Hydroxypropyl methylcellulose (HPMC) ndi chitsanzo cha cellulose ether yomwe imakhala yokhazikika komanso imagwira ntchito bwino mu putty powder.
Chidziwitso #5: Unikani Zosungirako Zosungira
Ma cellulose ether amakhudzidwa ndi kusintha kwa kutentha ndi chinyezi; Choncho, ziyenera kusungidwa pamikhalidwe yapadera kuti zisawonongeke. Ma cellulose ether ayenera kusungidwa pamalo owuma ndi kutentha ndi chinyezi kuti atsimikizire kukhazikika kwawo.
Ma cellulose ethers okhazikika amapangitsa kuti ufa wa putty ukhale wokhazikika, wokhazikika komanso wogwira mtima.
Chenjezo #6: Tsatirani njira zodzitetezera
Panthawi yopanga, kusamala kuyenera kuchitidwa kuti ogwira ntchito asakumane ndi ma cellulose ethers. Pogwira ma cellulose ethers, ndikofunikira kuvala zida zodzitetezera monga magolovesi, magalasi, ndi zishango zakumaso kuti musakhudze khungu, maso, kapena kupuma.
Kuphatikiza apo, ndikofunikira kulemba zilembo zomwe zili ndi ma cellulose ether okhala ndi machenjezo oyenera owopsa ndikutsatira njira zoyenera zotayira kuti zisawononge chilengedwe.
Pomaliza
Kusankha cellulose ether yoyenera pa putty powder ndikofunikira kuti mupeze zotsatira zapamwamba. Chenjezo liyenera kuchitidwa pozindikira mtundu ndi kalasi ya cellulose ether yofunikira, kuyesa kusungunuka kwake ndi kukhazikika kwa kutentha, kumamatira kusungirako koyenera, ndikutsatira njira zodzitetezera.
Kusamala izi sikungotsimikizira ubwino wa ufa wa putty, komanso kumateteza antchito ndi chilengedwe. Pogwiritsa ntchito ma cellulose ethers oyenera, ufa wa putty ukhoza kupangidwa motetezeka komanso mogwira mtima kuti ukwaniritse zofuna zamakasitomala komanso kusasinthasintha.
