Ntuj Roj Hmab Ntau Yam
Cov roj hmab ntuj tuaj yeem muab faib ua ob pawg tseem ceeb raws li nws daim ntawv: khoom siv roj hmab (cov ntawv roj hmab thiab cov roj hmab granular) thiab cov roj hmab uas muaj zog. Hauv kev siv txhua hnub, cov khoom siv roj hmab zoo rau feem coob. Cov ntawv roj hmab tuaj yeem muab faib ua cov ntawv roj hmab, cua- cov ntawv roj hmab qhuav, cov roj hmab dawb crepe, xim av crepe roj hmab, thiab lwm yam, raws li kev tsim khoom sib txawv thiab qhov tshwm sim. Cov ntawv haus luam yeeb roj hmab yog cov neeg sawv cev ntau yam ntawm cov roj hmab ntuj thiab yeej ib txwm yog hom roj hmab siv dav tshaj plaws.

Cov uas tsis tau raws li Qib 5 raug cais tawm ntawm qib - qib roj hmab. Granular roj hmab (piv txwv li, qauv roj hmab) tau muab qhab nia raws li kev sib koom ua ke thoob ntiaj teb lub cev thiab tshuaj lom neeg thiab cov ntsuas. Cov khoom ntawm lub cev thiab tshuaj lom neeg muaj xws li xya yam khoom: impurity cov ntsiab lus, tus nqi pib plasticity, plasticity retention rate, nitrogen cov ntsiab lus, volatile teeb meem cov ntsiab lus, cov hmoov tshauv, thiab xim Performance index. Ntawm cov no, cov ntsiab lus impurity yog qhov taw qhia ua ntej, thiab nws tau muab faib ua tsib qib: 5L, 5, 10, 20, thiab 50, raws li tus nqi ntawm impurities.
Kev siv tseem ceeb
Vim yog cov khoom siv ntawm lub cev thiab tshuaj lom neeg ntawm cov roj hmab uas tau hais los saum no, tshwj xeeb tshaj yog nws cov elasticity zoo heev, rwb thaiv tsev, dej tsis kam, thiab plasticity, thiab tom qab kev kho mob tsim nyog, nws kuj muaj cov khoom tseem ceeb xws li roj tsis kam, acid tsis kam, alkali tsis kam, kub tsis kam, txias tsis kam, siab tsis kam, thiab hnav tsis kam, yog li ntawd, nws muaj ntau yam kev siv. Piv txwv li, cov roj hmab ntuj yog siv rau hauv cov khoom siv niaj hnub xws li khau nag, lub raj mis dej kub, thiab cov hlua elastic; hauv kev kho mob thiab kev kho mob kev lag luam rau cov hnab looj tes phais, cov hlab ntshav, thiab cov hnab looj tes; hauv kev thauj mus los rau ntau hom log tsheb; nyob rau hauv kev lag luam rau conveyor siv, kis tau tus mob siv, thiab acid- thiab alkali- hnab looj tes tiv taus; nyob rau hauv kev ua liaj ua teb rau irrigation hoses thiab ammonia hnab; hauv kev ntsuas huab cua rau huab cua balloons; hauv kev sim tshawb fawb rau kev sib khi thiab kev poob siab- nqus cov khoom siv; nyob rau hauv lub teb chaws tiv thaiv rau aircraft, tso tsheb hlau luam, cannons, thiab gas qhov ncauj qhov ntswg; thiab txawm nyob rau hauv siab - cov khoom siv thev naus laus zis xws li foob pob hluav taws, satellites dag, thiab lub dav hlau.
