Kev siv hydroxypropyl methylcellulose, yuav ua li cas kom paub qhov txawv ntawm HPMC yooj yim thiab intuitively

Kev siv tseem ceeb ntawm hydroxypropyl methylcellulose yog dab tsi?

——Teb:HPMCyog siv dav hauv cov ntaub ntawv siv hauv kev tsim kho, tshuaj pleev xim, cov khoom siv ua los ntawm cov khoom siv av nplaum, tshuaj, khoom noj, textiles, kev ua liaj ua teb, tshuaj pleev ib ce, luam yeeb thiab lwm yam lag luam. HPMC tuaj yeem muab faib ua qib tsim kho, qib zaub mov thiab qib tshuaj raws li lub hom phiaj. Tam sim no, feem ntau ntawm cov khoom lag luam hauv tsev yog qib tsim kho. Hauv qib tsim kho, hmoov putty siv ntau heev, kwv yees li 90% yog siv rau hmoov putty, thiab qhov seem yog siv rau cov cement mortar thiab kua nplaum.

Yuav ua li cas kom paub qhov txawv ntawm HPMC yooj yim thiab intuitively?

——Teb: (1) Dawb: Txawm hais tias dawb tsis tuaj yeem txiav txim siab seb HPMC puas yooj yim siv, thiab yog tias cov neeg sawv cev dawb ntxiv thaum lub sijhawm tsim khoom, nws yuav cuam tshuam rau nws qhov zoo. Txawm li cas los xij, feem ntau ntawm cov khoom zoo muaj qhov dawb zoo. (2) Qhov zoo: Qhov zoo ntawm HPMC feem ntau muaj 80 mesh thiab 100 mesh, thiab 120 mesh tsawg dua. Feem ntau HPMC tsim tawm hauv Hebei yog 80 mesh. Qhov zoo dua qhov zoo, feem ntau hais lus, qhov zoo dua. (3) Kev xa hluav taws xob: muab hydroxypropyl methylcellulose (HPMC) rau hauv dej los tsim cov colloid pob tshab, thiab saib nws qhov kev xa hluav taws xob. Qhov ntau dua qhov kev xa hluav taws xob, qhov zoo dua, qhia tias muaj cov insolubles tsawg dua hauv nws. . Qhov permeability ntawm cov reactors ntsug feem ntau zoo, thiab ntawm cov reactors kab rov tav yog qhov phem dua, tab sis nws tsis txhais tau tias qhov zoo ntawm cov reactors ntsug zoo dua li ntawm cov reactors kab rov tav, thiab qhov zoo ntawm cov khoom yog txiav txim siab los ntawm ntau yam. (4) Lub ntiajteb txawj nqus tshwj xeeb: Qhov loj dua qhov hnyav tshwj xeeb, qhov hnyav dua qhov zoo dua. Qhov tshwj xeeb yog loj, feem ntau vim tias cov ntsiab lus ntawm hydroxypropyl pawg hauv nws yog siab, thiab cov ntsiab lus ntawm hydroxypropyl pawg yog siab, cov dej khaws cia zoo dua. (5) Hlawv: Siv ib feem me me ntawm cov qauv thiab hlawv nws nrog hluav taws, thiab cov seem dawb yog tshauv. Cov khoom dawb ntau dua, qhov tsis zoo, thiab yuav luag tsis muaj cov seem hauv cov khoom ntshiab.

Tus nqi ntawm hydroxypropyl methylcellulose yog dab tsi?

—–Teb; tus nqi ntawm hydroxypropylmethyl nyob ntawm nws qhov kev huv thiab cov tshauv. Qhov siab dua qhov kev huv, qhov tsawg dua cov tshauv, tus nqi siab dua. Txwv tsis pub, qhov qis dua qhov kev huv, qhov ntau dua cov tshauv, tus nqi qis dua. Ton rau 17,000 yuan ib ton. 17,000 yuan yog cov khoom ntshiab uas yuav luag tsis muaj cov khoom tsis huv. Yog tias tus nqi chav tsev siab dua 17,000 yuan, qhov nyiaj ntawm cov chaw tsim khoom tau nce ntxiv. Nws yooj yim pom seb qhov zoo puas zoo lossis phem raws li qhov ntau ntawm cov tshauv hauv hydroxypropyl methylcellulose.

Qhov viscosity ntawm hydroxypropyl methylcellulose yog dab tsi rau cov hmoov putty thiab mortar?

—–Teb; hmoov putty feem ntau yog 100,000 yuan, thiab qhov yuav tsum tau siv mortar siab dua, thiab nws xav tau 150,000 yuan kom yooj yim siv. Ntxiv mus, qhov tseem ceeb tshaj plaws ntawmhydroxypropyl methylcelluloseyog kev khaws dej, ua raws li kev tuab. Hauv cov hmoov putty, tsuav yog qhov khaws dej zoo thiab qhov viscosity qis (70,000-80,000), nws kuj ua tau. Tau kawg, qhov viscosity qis dua 100,000 yog siab dua, thiab qhov khaws dej zoo dua. Thaum qhov viscosity tshaj 100,000, qhov viscosity muaj feem cuam tshuam rau kev khaws dej. Qhov cuam tshuam tsis zoo.
