Yuav luag txhua leej txhua tus tau ntsib lo lus "hmoov". Nws muaj ntau heev nyob rau hauv lub neej txhua hnub. Tab sis tsis muaj coob leej xav txog nws keeb kwm. Hais txog dab tsi "hmoov" yog, nws hom thiab kev siv, tom qab hauv kab lus.
Lo lus hauv phau ntawv txhais lus
Yuav kom nkag siab tias hmoov yog dab tsi, cia peb tig mus rau phau ntawv txhais lus piav qhia, uas muab cov lus piav qhia hauv qab no. Qhov no yog lub xeev ntawm cov khib nyiab uas tau raug txo mus rau qhov siab tshaj plaws mechanically lossis lwm yam. Cov particles tsis txuas nrog ib leeg, vim tias cov hmoov muaj qhov tsis txaus ntseeg, tsis muaj qhov sib xws.
Lawv tau siv dav hauv ntau qhov kev lag luam, hauv kev lag luam hauv tebchaws.
Nws tsim nyog hais txog lub hauv paus ntawm lo lus. "Powder" yog ib daim ntawv me me ntawm lo lus "phom".

Txuas ntxiv lub ntsiab lus ntawm "hmoov" yog dab tsi, ntau hom yuav tsum muaj npe nyob ntawm qhov kev thov, uas yog:
- tshuaj;
- dental;
- abrasive;
- kev sib cav;
- graphite;
- magnesia;
- talc;
- hmoov;
- washing;
- xim;
- hmoov;
- phom.
Raws li koj tuaj yeem pom, lo lus yog siv los sau cov tshuaj siv hauv ntau yam. Cia peb saib qee qhov nthuav dav ntxiv.
Tshuaj
Kawm seb "hmoov" yog dab tsi, cia peb xav txog ib yam ntawm nws cov khoom siv feem ntau - tshuaj. Nov yog daim ntawv kho mob uas npaj rau kev siv sab nraud lossis sab hauv.
daim ntawv no muaj ntau qhov zoo, piv txwv li:
- nce thiab txhim kho cov txiaj ntsig kho;
- yooj yim thaum npaj ntau yam sib tov;
- technological simplicity;
- kev yooj yim ntawm kev thauj mus los;
- nce txee lub neej piv rau cov ntaub ntawv ua kua ntawm tib yam tshuaj.
Ntxiv rau qhov muaj txiaj ntsig ntau, cov hmoov tshuaj muaj qee qhov tsis zoo, xws li:
- nrawm decomposition ntawm cov tshuaj nquag nyob rau hauv kev cuam tshuam ntawm gastric kua txiv;
- khaus khaus;
- qeeb ntawm kev ua ntawm cov tshuaj hauv lub cev piv rau cov kua dej;
- hmoov, yog khaws cia tsis raug, feem ntau ua ntub dej, cov tshuaj nquag ploj mus.
Cov hmoov tshuaj yog cais los ntawm cov khoom xyaw, ntau npaum li cas, txoj kev thov. Nws yuav tsum tau muab sau tseg tias nws yog tsis yooj yim sua kom paub meej tias daim ntawv npaum li cas yog zoo dua, nws tag nrho yog nyob ntawm seb tus kab mob, tus yam ntxwv ntawm tus neeg mob nws tus kheej, cov tshuaj siv, tus kheej.nyiam (qee zaum, yog vim li cas, nws yog qhov zoo dua rau tus neeg mob noj cov hmoov).
Ntxhais
Tej zaum qhov nto moo tshaj plaws thiab feem ntau ntawm ntau hom hmoov yog ntxuav. Lawv cov kev hloov kho niaj hnub no muaj tag nrho cov khoom sib xyaw ntawm ntau yam, suav nrog: cov tsis-ionic thiab anionic surfactants (surfactants), dej qab zib, sulfate thiab sodium silicate (qee zaum sodium chlorides).
Ntxuav hmoov yuav muaj ob qho tib si kho qhov muag thiab tshuaj pleev ib ce, cationic surfactants, fragrances, ntau yam binders, xab npum thiab xim additives. Nws tau raug suav hais tias yog ib qho tshuaj ntxhua khaub ncaws nrov rau lub sijhawm ntev.
Txawm li cas los xij, tsis ntev los no, ntau tus neeg nyiam siv tsis yog hmoov, tab sis gel rau ntxuav. Qhov no yog vim tsis yog ntau heev rau kev tshaj tawm ntawm cov khoom, tab sis rau ntau qhov zoo ntawm qhov kawg. Piv txwv li, kev siv nyiaj ntau dua thiab tus nqi tsim nyog. Gels tsis tawm streaks ntawm cov khaub ncaws, uas feem ntau yog thaum siv ntxhua khaub ncaws. Txawm hais tias qhov no qhov teeb meem tseem ceeb yog kev ua haujlwm tsis raug ntawm AGR.
xim
Kawm lub ntsiab lus ntawm lo lus "hmoov", nws yog ib qho tsim nyog yuav tsum tau kov ntawm thaj chaw xws li kev lag luam. Nyob rau hauv lub 50s ntawm lub xyoo pua 20th, ib txoj kev tshiab tau tsim rau dyeing ntau yam ntaub ntawv. Nws tau raug hu ua "hmoov" thiab dhau los ua lwm txoj hauv kev rau "kua" xim daim ntawv thov.
Nws lub hauv paus ntsiab lus yog raws li hauv qab no: ntawm qhov chaw npajtxau nrog cov hmoov tshwj xeeb. Cov xim pleev xim los ntawm ib qho chaw sab nraud tau txais cov nqi hluav taws xob thiab raug xa mus rau cov khoom lag luam nrog kev pab los ntawm cov hluav taws xob, cov xim pleev xim ntau dhau yog ntes los ntawm lub tshuab cua tshwj xeeb. Tom qab ntawd, cov khoom raug xa mus rau lub chamber tshwj xeeb rau "ci", polymerization.
Tom qab qee lub sijhawm, lub zog muaj zog, txheej txheej monolithic yog tsim rau saum npoo ntawm cov khoom hauv chav. Daim ntawv thov Monolithic tau ua tiav vim qhov tseeb tias cov khoom sib npaug sib npaug ntawm cov khoom yuav tsum tau pleev xim rau vim qhov hluav taws xob.
Lub tshuab hluav taws xob polymerization hu ua "ci", ntxiv rau kev txhim kho qhov pom kev zoo ntawm cov khoom, nce lub zog thiab lub neej ntawm cov xim pleev xim.
Qhov no tso cai tsis yog tsuas yog ua cov hlau, ceramic, carbon thiab lwm yam, tab sis kuj ua rau nws siv tau rau ntau qhov chaw uas tsis tau npaj ua ntej. Piv txwv li, ntoo nto coated nrog ib tug polymer tsis ntshai ntawm ya raws thiab siv tau, piv txwv li, rau kev tsim cov rooj tog hauv chav dej.
