Irbad dab- celis ah oo dab-damis ah oo feertay dhar aan tolnayn

Qaybta ugu muhiimsan ee dab-damiska polyester-ka ee dharka aan timaha lahayn waa polyester, taas oo ah wax soo saarka polymerization ee terephthalic acid ama diethyl terephthalate iyo ethylene glycol. Sifooyinku waa sida soo socota: xoog sare, dabacsanaan wanaagsan, caabbinta kulaylka wanaagsan, dusha siman, caabbinta xirashada wanaagsan, caabbinta iftiinka wanaagsan, caabbinta daxalka, iyo waxqabadka midabaynta oo liita. Habka dab-demiska inta badan waxa uu ku lug leeyahay kordhinta dab-demiska, kuwaas oo ah nooc wax lagu daro oo caadi ahaan loo isticmaalo balaastigga polyesterka, dunta, iwm

Kala soocida dab-demiska ololka

Waxaa jira noocyo badan oo dab-damis ah, oo ay ku jiraan dib-u-dhigeyaasha ololka halogenated, organophosphorus iyo fosfooraska dab-dejiyaha ololka, dib-u-celinta ololka, iyo dib-u-dhigeyaasha ololka aan noolayn. Waqtigan xaadirka ah, dib-u-dhigeyaasha ololka broiled ayaa caadi ahaan loo isticmaalaa dib-u-dhigeyaasha ololka halogenaysan.

Codsiga maro aan toliyaha lahayn oo ololka celisa

Dharka Yang Ran ee aan dunta ka samaysan waxaa inta badan loo isticmaalaa fadhiga fadhiga, alaabta guriga jilicsan, furaashyada, alaabta lagu ciyaaro, alaabta guriga, dharka, iwm.

Shuruudaha xukunka ee maro aan tolnayn oo ololka retardant

1. Waxtarka kuleylku ma dhaafi karo 80 kilowatts.

2. 10 daqiiqo kahor, wadarta kuleylku waa inuusan dhaafin 25 MJ.

3. Isku-duubnaanta CO ee laga sii daayay muunada waxay ka badan tahay 1000 PPM in ka badan 5 daqiiqo.

4. Marka gubanaya maro aan tol lahayn oo ololaysa, cufnaanta qiiqu waa in aanu ka badnayn 75%.

5. Dab-dejinta maro aan-dhogorta lahayn waa caddaan saafi ah, oo leh jilicsanaan jilicsan, gaar ahaan barti wanaagsan iyo qoyaanka qoyaanka, taas oo ka dhigaysa mid aad u jecel dadka.

6. Isticmaalka fiilooyinka ololka dabiiciga ah ee dabiiciga ah, ma jiraan wax dhibco dareere ah.

7. Waxay leedahay saameyn is-daminta waxayna sameysaa lakab cufan oo carbide ah inta lagu jiro habka gubashada. Waxa ku jira kaarboon laba ogsaydh yar waxa ay soo saartaa qadar yar oo qiiq sun ah.

8. Maro aan toliyaha lahayn oo ololaysa waxay leedahay alkalinity deggan iyo iska caabin aashitada, ma aha sun, mana soo saarto fal-celin kiimikaad.

Tijaabinta maro aan tolnayn oo ololka celisa

Maro aan toliyaha lahayn ee ololka celisa ayaa leh dabcelis iyo sifooyin liddi ku ah dhibicda, kuwaas oo si wax ku ool ah u samayn kara dab-damiska ololka.

① US CFR1633 nuxurka tijaabada: Muddo 30 daqiiqo gudahood ah, kulaylka ugu sarreeya ee joodariga ama gogoldhigga waa in aanu dhaafin 200 kilowatts (KW), iyo 10 ka daqiiqo ee ugu horreeya ee la sii daayo, wadarta kuleylku waa in uu ka yaraado 15 megajoules (MJ).

Isticmaalka: Inta badan waxaa loo isticmaalaa joodariyaasha, barkimada fadhiga, fadhiga fadhiga, kuraasta, iyo alaabta guriga.

② Heerarka tijaabada ee ugu weyn ee British BS5852 waxaa ka mid ah tijaabinta dabada sigaarka iyo ku-dheellitirka taraqyada ololka acetylene, iyo sidoo kale ilaalinta dhererka burburka. Asal ahaan, nalalka fudud ayaa loo isticmaalaa in si toos ah loogu gubo dusha sare ee dunta 20 ilbiriqsi, ololkuna si toos ah ayuu u dami 12 ilbiriqsi gudahood ka dib marka uu ka tago ololka.

③ US 117 nuxurka tijaabada: Tijaabada sigaarka, oo aan ka badnayn 80% qaybta kulaylka badan, aan ka badnayn 3 inches ee dhererka gubashada celceliska, aan ka badnayn 4 inji oo dhererka gubashada weyn, aan ka badnayn 4 ilbiriqsi ee wakhtiga gubashada celceliska, wax aan ka badnayn 8 ilbiriqsi oo wakhti dheer ah gubasho, iyo in aan ka badnayn 4% khasaaraha baaxadda inta lagu jiro gubashada ololka furan.
