Sakanizani brake fluid ndi bulichi. Kodi chidzachitike n'chiyani?
Zamkatimu
Kupanga zigawo zikuluzikulu ndi reagents
Brake fluid ili ndi polyglycols - polymeric mitundu ya polyhydric alcohols (ethylene glycol ndi propylene glycol), boric acid polyesters ndi modifiers. Chlorine imaphatikizapo hypochlorite, hydroxide ndi calcium chloride. The reagent waukulu mu ananyema madzimadzi ndi polyethylene glycol, ndi bulitchi - hypochlorite. Palinso mtundu wamadzimadzi wa zinthu zapakhomo zomwe zili ndi klorini, momwe sodium hypochlorite imakhala ngati oxidizing.
Ndondomeko yamachitidwe
Mukasakaniza bleach ndi brake fluid, mutha kuwona kukhudzidwa kwakukulu ndikutuluka kwa gasi wochuluka. Kuyanjana sikuchitika nthawi yomweyo, koma pambuyo pa masekondi 30-45. Pambuyo pakupanga geyser, zinthu za gasi zimayaka, zomwe nthawi zambiri zimatha ndi kuphulika.
Sitikulimbikitsidwa kuchita kuyesera kunyumba. Pochita izi, zida zodzitetezera ziyenera kugwiritsidwa ntchito, ndipo zomwe zimachitikazo ziyenera kuchitika mu fume hood kapena pamalo otseguka patali.
kachitidwe kachitidwe
Poyesera, bleach wokonzedwa mwatsopano amagwiritsidwa ntchito. M'malo bulichi, mungagwiritse ntchito sodium hypochlorite, yomwe ili ndi 95% yogwira chlorine. Pachiyambi, mchere wa hypochlorite umawonongeka ndi mapangidwe a atomiki klorini:
NaOCl → NaO+ + CI-
The chifukwa kolorayidi ion amaphulitsa molekyulu ya ethylene glycol (polyethylene glycol), zomwe zimabweretsa kusokoneza dongosolo la polima ndikugawanso kachulukidwe ka elekitironi. Zotsatira zake, monomer, formaldehyde, imasiyanitsidwa ndi unyolo wa polima. Molekyu ya ethylene glycol imasandulika kukhala electrophilic radical, yomwe imakhudzidwa ndi ion chloride ina. Pa gawo lotsatira, acetaldehyde imasiyanitsidwa ndi polima, ndipo pamapeto pake alkene yosavuta kwambiri, ethylene, imakhalabe. General breakdown scheme ili motere:
Polyethylene glycol ⇒ Formaldehyde; Acetaldehyde; Ethylene
Kuwonongeka kowononga kwa ethylene glycol pansi pa zochita za klorini kumayendera limodzi ndi kutuluka kwa kutentha. Komabe, ethylene ndi formaldehyde ndi mpweya woyaka. Chifukwa chake, chifukwa cha kutentha kwazomwe zimachitika, zinthu za gasi zimayaka. Ngati kuchuluka kwa zomwe zimachitika mwachangu kwambiri, kuphulika kumachitika chifukwa cha kufalikira kwapawiri kwa osakaniza amadzimadzi.
Chifukwa chiyani zomwe sizikuchitika?
Nthawi zambiri mukasakaniza brake fluid ndi bulichi, palibe chomwe chimawonedwa. Izi zimachitika pazifukwa zotsatirazi:
- Anagwiritsidwa ntchito bulitchi yakale ya m'nyumba
Akasungidwa panja, calcium hypochlorite imawola pang’onopang’ono kukhala calcium carbonate ndi calcium chloride. Zomwe zili mu klorini yogwira zimachepetsedwa mpaka 5%.
- Kutentha kochepa
Kuti izi zitheke, ndikofunikira kutenthetsa madzi a brake mpaka kutentha kwa 30-40 ° C
- Sipanapite nthawi yokwanira
Kuchita kwakukulu kwa unyolo kumachitika ndikuwonjezeka pang'onopang'ono kwa liwiro. Zidzatenga pafupifupi mphindi imodzi kuti zosintha zowoneka ziwonekere.
Tsopano mukudziwa zomwe zidzachitike ngati bulitchi ikasakanizidwa ndi brake fluid ndi momwe kuchitirako kumachitika.
