Cellulose ethers zvinhu zvakajairika zvinoshandiswa mukugadzirwa kwependi uye machira senge putty poda.Putty ihupfu-based filler inoshandiswa kuzadza mapundu, makatsemuka uye maburi mune chero nzvimbo.Cellulose ether inovandudza kunaka kweputty powder nekuvandudza kunamatira kwayo, kubatana uye zvimwe zvinhu zvemuviri.Pakusarudza cellulose ethers yeputty poda, matanho anodiwa anofanirwa kutorwa kuve nechokwadi chemhando yepamusoro.
Inopa hutungamiri hwakakwana panyaya dzinofanirwa kutariswa pakusarudza cellulose ether ye putty powder.
Cherechedzo #1: Sarudza rudzi rwe cellulose ether inodiwa
Kune mhando dzakasiyana dze cellulose ethers, dzinosanganisira methylcellulose, ethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, uye carboxymethylcellulose.Imwe neimwe mhando ye cellulose ether ine yakasarudzika zvimiro inoita kuti ive yakakodzera kune chaiwo maapplication.Nokudaro, usati wasarudza cellulose ether ye putty powder, zvakakosha kuziva rudzi rwe cellulose ether yakakodzera rudzi rweputty powder inogadzirwa.
Semuenzaniso, hydroxyethyl cellulose (HEC) yakanyatsokodzera kushandiswa mu putty powders nokuti inowedzera rheological properties ye putty powder.HEC inokora mhinduro, inodzivirira kudonha, uye inowedzera viscosity yeputty poda.Methylcellulose, kune rumwe rutivi, haina kukodzera kushandiswa muputty powder nokuti haina kufanana kwakafanana neHEC.
Cherechedzo #2: Sarudza giredhi ye cellulose ether inodiwa
Cellulose ethers inowanikwa mumagiredhi akasiyana zvichienderana nekuchena uye kuisa pfungwa.Chiratidzo che cellulose ether chinodiwa kuti putty powder chigadziriswe maererano nezvinodiwa zveputty powder.
Kuchena-kuchena mamakisi e-cellulose ethers anosarudzwa pane yakaderera-giredhi cellulose ethers nekuti anovimbisa kuenderana kushanda kweputty powder.High-purity cellulose ether haina madota, zvakasara uye zvimwe zvinosvibisa zvinokanganisa kunaka kweputty powder.
Cherechedzo #3: Kuongorora Solubility yeCellulose Ethers
Cellulose ethers inonyungudika mumvura, asi chiyero chekunyungudika chinosiyana zvichienderana nerudzi rwe cellulose ether.Hydroxypropylcellulose (HPC) muenzaniso we cellulose ether isinganyunguriki mumvura;pachinzvimbo, inopararira nyore nyore mumvura.
Izvo zvakakosha kuti uone kunyungudika kweiyo cellulose ether inoshandiswa muputty poda kuve nechokwadi kuti inonyungudika mumvura uye haikonzerese kukoromoka kana kusawirirana mune putty poda.
Cherechedzo #4: Funga nezveTembiricha Yekushandisa
Iyo tembiricha yekuvaka ye putty powder cellulose ether zvakare yakakosha kufunga.Imwe neimwe mhando ye cellulose ether ine chaiyo tembiricha yemhando iyo inoshanda zvakanyanya.Naizvozvo, zvakakosha kuti usarudze cellulose ethers inokwanisa kumira tembiricha yekuvaka yeputty poda.
Cellulose ether ine kugadzikana kwakanaka kwekushisa uye yakakodzera kushandiswa mu putty powder nokuti haizodzikisi kana kukundikana pakupisa kwakanyanya.Hydroxypropyl methylcellulose (HPMC) muenzaniso we cellulose ether iyo inogadzikana ye thermally uye inoshanda zvakanaka mu putty powder.
Cherechedzo #5: Ongorora Mamiriro Ekuchengetedza
Cellulose ethers inonzwa kune kuchinja kwekushisa uye hunyoro;saka, dzinofanirwa kuchengetwa pasi pemamiriro chaiwo kudzivirira kudzikisirwa.Cellulose ethers inofanira kuchengetwa panzvimbo yakaoma ine tembiricha inodzorwa uye hunyoro kuitira kuti dzive dzakagadzikana.
Yakagadzikana cellulose ethers inovandudza kunaka kweputty powder, ichiita kuti iwedzere kuwirirana, yakasimba uye inobudirira.
Chengetedzo #6: Tevedzera kuchengetedza
Munguva yekugadzira, kungwarira kunofanirwa kutorwa kudzivirira kuratidzwa kwevashandi kune cellulose ethers.Paunenge uchibata cellulose ethers, zvakakosha kuti upfeke midziyo yekudzivirira senge magurovhosi, gogi, uye nhovo dzechiso kudzivirira kubata neganda, maziso, kana kufema system.
Pamusoro pezvo, zvakakosha kuisa mucherechedzo mumidziyo ine cellulose ether ine zviratidzo zveyambiro yengozi uye kutevedzera nzira dzakakodzera dzekurasa kudzivirira kusvibiswa kwezvakatipoteredza.
mukupedzisa
Kusarudza iyo chaiyo cellulose ether yeputty poda kwakakosha kuti uwane mhedzisiro yemhando yepamusoro.Kuchenjerera kunofanirwa kutorwa pakusarudza mhando uye giredhi ye cellulose ether inodiwa, kuongorora kunyungudika kwayo uye kugadzikana kwekupisa kwayo, kuomerera kumamiriro ekuchengetedza kwakaringana, uye kutevera matanho ekuchengetedza.
Kutora zvidziviriro izvi kwete chete kuvimbisa kunaka kweiyo putty poda, asiwo inodzivirira vashandi uye nharaunda.Uchishandisa iyo chaiyo cellulose ethers, putty poda inogona kugadzirwa zvakachengeteka uye nemazvo kuzadzisa zvinodiwa nevatengi zvemhando uye kuenderana.
