Cov lus qhia:

Nws yog feem ntau siv los ua rum flavour thiab txiv hmab txiv ntoo flavors. Nws kuj tseem siv tau ua kuab tshuaj hnyav. Hauv kev siv tshuaj, nws yog feem ntau yog siv los ua cov tshuaj ntxuav kom huv rau lub hauv paus ntawm cov khoom. Rau cov organic synthesis. Siv raws li kev xav reagent.

1. Qaug dej kho thaum muaj xwm ceev

Txiav tawm qhov hluav taws kub. Looj roj qhov ncauj qhov ntswg thiab cov tshuaj tiv thaiv chemical. Tsis txhob ncaj qha rau nrog cov paim quav, thiab nres qhov chaw yaim qis raws li kev ua kom muaj kev nyab xeeb. Cov tshuaj tsuag txau tuaj yeem txo cov evaporation. Nws yog nqus los ntawm xuab zeb, vermiculite lossis lwm yam khoom siv sab hauv, thiab tom qab ntawd thauj mus rau qhov chaw qhib rau kev faus, evaporation lossis kev kub nyhiab. Yog tias muaj qhov tshwm sim loj ntawm cov dej txeej, nws yuav tsum sau thiab rov ua dua tshiab los yog muab pov tseg.

2. Kev ntsuas tiv thaiv

Kev tiv thaiv pa tawm: thaum lub siab nyob hauv huab cua siab dhau tus qauv, koj yuav tsum hnav lub npog ntsej muag roj.

Qhov muag tiv thaiv: looj tsom iav qhov muag tshuaj lom neeg.

Kev tiv thaiv lub cev: hnav khaub ncaws tiv thaiv kev ua haujlwm.

Tes tiv thaiv: looj hnab looj tes tiv thaiv.

Lwm tus: haus luam yeeb raug txwv tsis pub muaj nyob ntawm haujlwm. Tom qab ua haujlwm, da dej thiab hloov khaub ncaws. Them nyiaj tshwj xeeb rau kev tiv thaiv qhov muag thiab ua pa.

3. Thawj qhov ntsuas ua ntej

Kev tiv thaiv tawv nqaij: hle cov khaub ncaws uas muaj kab mob thiab ntxuav kom huv nrog xum npum thiab dej.

Qhov muag hu rau lub qhov muag: tam sim qhib lub qhov muag sab saud thiab qis qis thiab yaug nrog dej ntws rau 15 feeb. Ntsib kws kho mob.

Kev nqus tau: tawm ntawm qhov xwm txheej mus rau huab cua ntshiab. Muab pa oxygen thaum koj ua pa nyuaj. Thaum ua tsis taus pa nres, ua pa tawm ntawm lub cev yuav tsum ua tam sim ntawd. Ntsib kws kho mob.

Kev noj haus: yog siv los ntawm kev ua yuam kev, haus dej sov txaus, ua rau ntuav thiab pom tus kws kho mob.

Cov kev tua hluav taws: dej pos huab, npuas dej, carbon dioxide, hmoov qhuav thiab xuab zeb.

Cov cwj pwm txaus ntshai: thaum qhib hluav taws, muaj cua sov lossis tiv toj nrog oxidant, muaj kev pheej hmoo ntawm kev sib tsoo thiab tawg. Thaum muaj cua sov, polymerization cov tshuaj tiv thaiv yuav tshwm sim, uas ua rau muaj ntau ntawm exothermic cov xwm txheej, uas ua rau lub nkoj tawg thiab tawg qhov xwm txheej. Nws lub vapor yog qhov hnyav dua li huab cua, nws tuaj yeem sib kis mus rau qhov kev txiav txim siab ntawm qhov chaw qis, thiab nws yuav ua rau kom Rov Tau Ruaj Ntseg yog tias qhib hluav taws.

Cov: 180kg / nruas.

Lub peev xwm txhua xyoo: 1000 tons / xyoo
