Tuubbooyinka isku dhafan ee birta daloolin waxay ka samaysan yihiin bir bir ah oo qabow-duuban iyo heerkulbeegyo sida alaab cayriin ah, iyo tuubooyinka birta dhuuban ee dhuuban ee ay sameeyeen alxanka dabada dabada ee argon ama alxanka balaasmaha ayaa loo isticmaalaa xoojin ahaan. Lakabyada dibadda iyo gudaha waa heerkulbeegyo isku dhafan oo laba-dhinac ah. Nooca cusub ee tuubada cadaadiska isku dhafan, Sababtoo ah xoojinta tuubooyinka birta dhuuban ee dhuuban waxaa lagu duuduubay heerkulbeegga joogtada ah, tuubadaan isku dhafan kaliya kama adkaanayso cilladaha u gaarka ah ee tuubooyinka birta iyo tuubooyinka caagga ah, laakiin sidoo kale waxay leedahay adkaanta tuubooyinka birta iyo daxalka caabbinta tuubooyinka caagga ah. Waxay xal u tahay warshadaha batroolka iyo kiimikada. Waa dhuumo si degdeg ah loogu baahan yahay oo ah dhuumo waaweyn iyo dhexroor dhexdhexaad ah oo ku yaal beeraha dawooyinka, cuntada, macdanta, gaaska iyo beeraha kale. Sidoo kale waa guul tignoolajiyadeed kacaan si loo xalliyo dhuumaha ugu muhiimsan ee dhismaha iyo biyo-gelinta dawladda hoose. Waa nooc cusub oo ah dhuumaha isku dhafan ee 21kastqarniga.
Xoog sare iyo fidinta toosan ee hooseeya.
Iyadoo ay ugu wacan tahay xoojinta qaabka birta, tuubada balaastikada ah ee fiilada birta ah ee daloolku waxay leedahay awood sare, qallafsanaan sare iyo iska caabin saameyneed marka loo eego tuubada caagga ah. Isla mar ahaantaana, saamaynta xakamaynta ee qaabka birta ayaa sidoo kale ka dhigaysa birta daloolin ee tuubada isku dhafan ee caagga ah waxay leedahay khad hoose oo la mid ah kan tuubada birta. Isbahaysiga ballaarinta iyo iska caabinta сгеер.
Daxalka iyo xidhashada iska caabbinta.
Maaddada polyetylenka ee cufnaanta sare leh ee loo xushay birta daloolin ee birta daloolinaysa tuubada caagga ah ee isku dhafan waa walxo polymer-ka-ka-soo-baxa ah oo leh waxyaabo kiimiko ah oo deggan, iska caabin u ah inta badan aashitada, cusbada alkali iyo warbaahinta organic, iyo daxalka korantada. Waxqabadka shiidadu 5 jeer ayuu ka sarreeyaa tuubooyinka birta.
Alaabtani waxay isticmaashaa xabagta polyetylen gaar ah, iyo alaabteeda jidheed iyo farsamaysanba waxay la kulmeysaa heerka wasaarada dhismaha CJ/T181-2003 iyo heerka warshadaha kiimikada HG/T3706-2014.

Fiiro gaar ah: Cadaadiska magaca ah ee tuubada isku dhafan waa cadaadiska ugu badan ee loo oggol yahay tuubada inay ku qaado biyaha 20 ° C. Haddii heerkulku isbeddelo, cadaadiska shaqada waa in la saxo iyadoo loo eegayo isku-dhafka heerkulka heerkulka ee walxaha kala duwan. Qiimaha S: fogaanta dhexroorka dibadda ee xoojinta ilaa dusha sare ee tuubada. |
