Midandlings yar, sida galka aan habooneyn ama nadiifinta aan ku filnayn, waxay u horseedi kartaa weecashooyin macluumaad weyn, oo daraasado muujinaya ilaa 30% kala duwanaanshaha natiijooyinka.
Maqaalka ayaa u beddelay arrimaha sida hubinta ciriiriga, dib u adeegsiga vials wasakhda ah, oo dayacaya isku-darka kiimikada ee ka dhexeeya agabyada vial iyo reaces-ka, iyo marin habaabinta mugdiga ah ee horseedda saamaynta lama huraanka ah.
Markaad bixiso xalal faahfaahsan iyo xogta ansaxinta tijaabada ah, maqaalka wuxuu kuyaala cilmi baarayaal kahortagaya in lagu hubiyo nidaamkooda tijaabada si loo hubiyo saxsanaanta xogta iyo isku halaynta.
1. Hordhac: khaladaad yaryar, cawaaqib weyn
Falanqaynta tusaalaha shucaaca, mishandsings-ka yar ee vials scials ee 20ML-ka ayaa u horseedi karta weecashada xogta illaa 30%, iyadoo cilmi-baarayaal badan ay ka warqabaan arrimaha salka ku haya.
Sida laga soo xigtay xogta ka soo baxyaashii caalamiga ah sida Thomas sayniska, oo aan habooneyn oo lagu isticmaalo vials scials akoonnada illaa 17% sicirka ku soo celinta tijaabada.
2. Shanta qaladaad oo caadi ah iyo xalalkooda
Khaladaadka 1: Keenidda xirashada ee aan ku filneyn ee muunad muunad ah
Muuqaalka caadiga ah: Kaliya wareegga daboolka 1 \ / 4 leexashada, oo ku guuldareysta inaad gaarto CS222 naqshadda khidmadda 3 \ / 4
-
Qiimaha asalka ee sareeya ee ogaanshaha ery ray.
-
Qiimaha qalloocan ee tirinta sanballada dhaqdhaqaaqa ee hooseeya.
Xalka: Hubso in daboolku aad u adkeeyay heerka qaabeynta, iyadoo la adeegsanayo koofiyadaha lagu xardhay polyettyne-ka si kor loogu qaado sharafta xirashada.
Khaladaadka 2: Dib u adeegsiga vials iyada oo aan la nadiifin
Khataraha haraaga ah: Haraaga dareeraha ku saleysan ee toluene-ku-saleysan ayaa laga yaabaa inay ka gudubaan faddarayn ku jirta dib-u-soo-celinta biyo-ku-laabashada biyaha.
Nadiifinta Talooyinka Talooyinka:
| Wax | Wakiilka nadiifinta ee lagu taliyay | Times Times Times |
|---|---|---|
| Galaas (vs2017) | Chromic acid acid → Biyaha Ultrapure | 50 jeer |
| Hdpe | Ethanol ultrasonic → Nitrogen Qalajinta | 30 jeer |
Xullo habab nadiifin ku habboon oo ku saleysan waxyaabaha si loo hubiyo muunadda saamiga.
Cilad 3: Iftiiminta isku-darka kiimikada ee ka dhexeeya agabyada iyo regient
Isbarbardhiga isbarbardhiga:
| Nooca dib u soo celinta | Quraarad | Hdpe | Xayawaan dab-joog | Tuubbo PP ah |
|---|---|---|---|---|
| Toluene \ / xylene | ✓✓✓ | ✓✓ | ✗ | ✓✓✓ |
| Aashito adag (ph <2) | ✓✓✓ | ✗ | ✗ | ✓✓ |
| Acetone | ✓✓ | ✓✓✓ | ✓✓ | ✓✓ |
Xullo agabyada vial ee la jaan qaadaya readiankaaga si aad uga fogaato fal-celinta kiimikada ee saameyn ku yeelan kara natiijooyinka tijaabada.
Cilad 4: Kaydinta aan habooneyn ee u horseedda faddaraynta jirka
Isbarbardhiga kiiska:
-
Kaydinta qumman ee kaydinta vs. Kaydinta toosan ee u horseedaya crotstallization ee afka huurka.
-
Difaaca iftiin oo aan ku filnayn oo keenaya buuq asal ah.
Talobixin: Xullo noocyada muraayadaha indhaha ee asalka ah (vs2017b) ama finalka iftiinka leh ee hdpe-shiil-gaashaandhiga si loo maareeyo saamiyo fudud.
