APP waxay wax ka beddeshay xuubabka bitumen
Xuubabka bitumen ee APP ee wax laga beddelay waxaa lagu sameeyaa iyadoo lagu buuxinayo saldhigga bitumen, ama heerkulbeegyada (sida APP, APAO, APO), ka dibna ku daboosha laba weji oo leh elastomer thermoplastic (SBS) oo ugu dambeyntii ku dhammaysata wejiga sare ee ciid wanaagsan, dhejisyo macdanta (ama badarka). ) ama xuubka polithene-ka iwm. halka uu hoos u socdo oo leh ciid wanaagsan ama xuubka polithene.
Sifada:
Waxyeelo la'aan wanaagsan;Hayso xoog jilicsan oo wanaagsan, heerka dhererka iyo xasilloonida cabbirka taas oo si fiican ugu habboon qallooca substrate-ka iyo dildilaaca;Xuubka bitumen ee la beddelay ee SBS ayaa si gaar ah loogu dabaqayaa aagga qabow ee heerkulkiisu hooseeyo, halka APP-da la beddelay ee xamaarka lagu dabaqo aagga kulul ee leh heerkul sarreeya;Waxqabadka wanaagsan ee ka-hortagga daloolada, ka-hortagga dilaaliinta, ka-hortagga-iska-caabbinta,-ka-hortagga-nabaad-guurka,-ka-hortagga caarada,-cimilada;Dhismuhu waa ku habboon yahay, habka dhalaalku wuxuu shaqayn karaa afar xilli, kala-goysyadu waa kuwo la isku halleyn karo

Baaxadda lagu dabaqi karo:
Ku habboon saqafka dhismaha madaniga ah, dhulka hoostiisa, buundada, baarkinka, barkadda, tunnelka khadka biyaha ka celinaya iyo qoyaanka, gaar ahaan dhismaha hoostiisa heerkul sare.Marka loo eego shardiga injineerinka saqafka, APP-da la beddelay ee xuubka bitumen waxaa loo isticmaali karaa Fasalka Ⅰ dhismaha madaniga ah iyo dhismaha warshadaha kaas oo leh shuruudo gaar ah oo biyuhu.
Tilmaamaha kaydinta iyo gaadiidka
l Marka kaydinta iyo gaadiidka, noocyada iyo cabbirka kala duwan ee alaabta waa in la is dulsaaran si gaar ah, waa in aan la isku qasan.Heerkulka kaydinta waa inuusan ka sarreyn 50 ℃, dhererku maaha in ka badan laba lakab, inta lagu jiro gaadiidka, xuubka waa inuu istaagaa.
l Dhererka is dulsaarku kama badna laba lakab.Si looga hortago leexinta ama cadaadiska, marka loo baahdo dabool dharka la dareemay.
l Xaaladaha caadiga ah ee kaydinta iyo gaadiidka, muddada kaydinta waa sannad tan iyo taariikhda wax soo saarka
