Xaalada wadooyinka ku xiran tahay addeecidda ee technology xaareysa laami

Xaqiiqada ah in sida laami, Dadka ayaa loo yaqaano muddo dheer. laami Dabiiciga ah (cusbi buurta ka kooban isku dar ah ee dhoobo leh qalabka macdanta) loo isticmaalaa xitaa Masriyiintii qadiimiga ah iyo sida Phoenicians gal ah in dhismaha dhismayaasha iyo maraakiibta. South American Indians isticmaalo laami si impregnate doonniyahoodii. Asphalt waxaa loo isticmaalay by Masriyiintii oo uu ugu mummification, oo ay East waxaa loo tixgeliyaa inay xal. Intaa waxaa dheer, laami dabiiciga ah ee sariirta Badda Dhimatay ka soo bixiyay, loo isticmaalo (oo weli isticmaalaan) si ay u abuuraan varnishes iyo rinjiga.

Codsiga of laami macmal ah (shinida dar is dulfuulan, dhagax la jajabiyey, ciid, budada macdanta) sida wax loogu xaaraya wadada bilaabay qarnigii XIX goor dambe Yurub iyo USA. Haddaba, waxaan bilaabay in ay dalban ah laami iyo Russia.

Dabcan, tan iyo technology seesdhiggooda ah, iyo wax soo saarka ayaa isbedelo weyn, laakiin mabaadi'da aasaasiga ah sidiisii.

dhismaha wadooyinka Modern

The xaalad ugu muhiimsan ee gaadiidka caadiga ah waa habka samaynta guryaha oogada waddada adag. Haddii aan faa'iido caadiga ah ee wadooyin laami casri ah waa wax macquul ah, oo sidaas daraaddeed dhismaha jidka wayn waa mudnaanta koowaad u ah dal kasta.

laami Compliance saareen technology iyo hufnaan si toos ah oo la xidhiidha kantaroolka-soo-saarka iyo tayada mid ah waxyaabaha la isticmaalo si ay u sameeyaan Laamiyo laami ah. Ka gaabinta in ay u hoggaansamaan natiijada in failure dhicis ah ee jidka.

The guulihii sayniska casriga ah ka samaysaa suurto gal ah in had iyo goorba wanaajiyo sida halabuurka ah qaybaha kala duwan ee laami ah, iyo nidaamka oo dhan ee wax soo saarka xagga shuqullada wadada.

Haddii aan ka hadlo technology ee laami, waxaa la sameeyaa in afar marxaladood:

• tababarka,
• kulaylinta laami si aad u jilciso,
• yeynan laami on saldhig;
• compactor Rolling-laami for compacting iyo waxa dheellitir.

Marka la dhameeyo of talaabooyinkan, laami waa in ay waqti ka hor inta Daaweynta dhameystiran, waxaana loo helo xoog design.

technology Taas oo muujinaysa xayiraad daran on amarka of tallaabooyin, waafaqsan caqabadaha cimilada iyo saadaasha hawada. Dhicitaanka in la raaco kuwaas oo loo baahan yahay (tus, isku xigxiga Sargaal Sare oo yaraada ama marka heerkulku hooseeyo, in roobka) keenaysaa in xaqiiqda ah in dhulka sallaxa ah socon doono wax ka yar sida caadiga ah.

Xataa u hogaansanaanta adag oo dhan teknoolajiyada laami jirto ballan qaad in oogada waddada ma u baahan yihiin dayactir dheeraad ah iyo dayactirka waqtiga.

Isticmaalka laami qabow, waayo, dayactirka waddooyinka

Macluumaadkaan waxaa u muuqday xad dhawaan dalkeena. Waxaa la sameeyey ka laami ah caadiga polymer-modified la raaciyay dhaxan iyo plasticizing daro. laami Cold technology saareen si weyn u fududeyneysa habsocodka ee dayactirka wadada, tan waxay u saamaxdaa in ay sameeyaan kala duwan heerkulka ballaadhan. Waxaa lagu rakibi karo marka heerkulku hooseeyo (-15 ° ^C). Intaa waxaa dheer, shuqullada wadada loo samayn karaa in roob. Waayo, yeynan qabow laami uma baahna daaweyn pre iyo daahan Primer cusboonaysiiyey. Laakiin faa'iido ugu muhiimsan in uu yahay laami qabow, - technology ee dhigin wax this uma baahna qalab gaar ah. Waa ku filan tahay in ay ku shub booddo ama god iyo majarafad barbareeyay, ka dib markii taas oo nidaamka polymerization bilaabmin iyo laami si deg deg ah engejiyaa. Sida qiimaha, haddii la barbar dhigo kharashka dayactirka wareegsan waddooyinka la laami caadiga ah, waxaa soo baxday in isticmaalka laami qabow noqon doonaa xataa ka jaban.
