Sharaxaada Isticmaalka Alaabta
(1) 1,2-Propanediol waa walxo muhiim ah oo ceeriin ah oo loogu talagalay polyester-ka aan la daboolin, resin epoxy, resin polyurethane, balaastik iyo surfactant.Polyester-kan aan saturated lahayn ayaa si weyn loogu isticmaalaa daaha-korka iyo balaastikada la xoojiyay.
(2) 1,2-Propanediol waxay leedahay viscosity wanaagsan iyo hygroscopicity, waxaana si ballaaran loo isticmaalaa sida wakiilka hygroscopic, antifreeze, saliidaha iyo dareeraha cuntada, daawada iyo warshadaha qurxinta.
(3) Warshadaha cuntada, 1,2-propylene glycol waxay la falgashaa asiidh dufan leh si ay u sameeyaan propylene glycol fatty acid esters, kuwaas oo inta badan loo isticmaalo emulsifiers cuntada;1,2-propylene glycol waa dareere aad u fiican oo loogu talagalay xashiishyada iyo midabada.Sunta yar awgeed, waxa loo isticmaalaa sida dareere udgoon iyo midabaynta cuntada ee warshadaha cuntada.
(4) 1,,2-Propanediol waxa si caadi ah loogu isticmaalaa warshadaha dawooyinka sida dareere, jilciya iyo udgoon loogu talagalay soo saarista boomaatada iyo boomaatada kala duwan, iyo sida wakiilka isku dhafka ah, ilaalinta, boomaatada, fitamiinada, Solvents sida penicillin.Sababtoo ah propylene glycol waxay leedahay milmo wanaagsan oo labada dhinac ah oo leh udgoon kala duwan, waxa kale oo loo isticmaalaa sida dareeraha iyo jilciye alaabta la isku qurxiyo, iwm.
(5), 1,2-Propanediol sidoo kale waxaa loo isticmaalaa sidii wakiilka qoyaan tubaakada, caariyaysi-celiyaha, dareeraha qalabka habaynta cuntada saliidda iyo khad calaamadinta cuntada.
(6) Xalka aqueous ee 1,2-propanediol waa ka hortag wax ku ool ah.Waxa kale oo loo isticmaalaa sida wakiilka qoynta tubaakada, caariyaysiga caariyaysiga, ilaalinta bislaanshaha miraha, ka-hortagga kuleylka iyo sidaha kulaylka, iwm.
Kaydinta
Tallaabooyinka maaraynta badbaadada leh: Ka fogow neefsashada ama la xidhiidh alaabtan.Isticmaal kaliya meelaha hawo-mareenka ah.Si fiican ugu dhaq biyo ka dib markaad qabato ama isticmaasho.
Shuruudaha kaydinta badbaadada leh: Inkasta oo alaabtani aanay si iskiis ah u shidi doonin, haddana waa gubanaysaa.Kaydinta muddada-dheer ma xumaan doonto, laakiin furitaanka ayaa nuugi doona qoyaanka.Kaydinta iyo weelasha gaadiidka waa in laga sameeyaa durbaannada birta ah ee galvanized, aluminium ama birta aan daahin.Kaydinta iyo gaadiidka iyadoo la raacayo qawaaniinta kiimikada guud ee sun-yar.Ka fogow xidhiidhka biyaha iyo deegaanka qoyan.Haamaha waa in ay ahaato mid nadiif ah, engegan oo aan miridhku ku jirin.Waa in lagu kaydiyaa meel leh darbi, hawo, iyo ka ilaalin cadceedda, olol furan iyo ilo kulaylka kale.Xiritaanka Nitrogen waxaa lagula talinayaa taangiyada kaydinta waaweyn (oo leh 100 m3 ama ka badan).Weelka si adag u xidh.Ku hay qalalan.
Heerkulka kaydinta: ilaa 40°C
Xiritaanka alaabta
- 215kg durbaan, 80 durbaan, Wadarta 17.2MT
- 22-23MT Flexibag
- 1000kg IBC, 20IBC, Wadarta 20MT
FAQS
1) Ma ku daabacan karnaa astaantayada alaabta?
Dabcan, waan sameyn karnaa.Kaliya noo soo dir nashqada astaantaada.
2) Ma aqbashaa amarro yaryar ?
HaaHaddii aad tahay dukaanle yar ama bilaabaya ganacsi, xaqiiqdii waxaan diyaar u nahay inaan kula korayno.Waxaan rajeyneynaa inaan kula shaqeyno xiriir waqti dheer ah.
3) Sidee ku saabsan qiimaha?Ma ka dhigi kartaa mid jaban ?
Had iyo jeer waxaan u qaadannaa faa'iidada macaamiisha sida mudnaanta ugu sareysa.Qiimaha waxaa lagu gorgortami karaa xaalado kala duwan, waxaan kuu xaqiijineynaa inaad hesho qiimaha ugu tartanka badan.
4) Ma bixisaa muunado bilaash ah?
Dabcan.
5) Ma awoodaa inaad wax ku keento waqtigii loogu talagalay?
Dabcan!waxaanu ku takhasusay khadkan sanado badan,macaamiil badan ayaa heshiis ila gala sababtoo ah waxaan keeni karnaa alaabta waqtigeeda oo aan ilaalin karno alaabta tayada sare!
6) Waa maxay shuruudaha lacag bixinta?
Waxaan caadi ahaan aqbalnaa T/T, Western Union, L/C.
