Ukusetyenziswa kwentambo yokufudumeza kombane kwi-insulation ye-pulp pipe yephepha

Amashishini okwenza amaphepha kwingingqi yaseMntla-mpuma anexesha lokugquma eliphantse libe ngama-200 eentsuku ngonyaka kwimibhobho yokubonelela ngepulp yangaphandle. Ekuqaleni, iinkampani ezininzi beziqhele ukusebenzisa ukufudumeza umphunga ukugquma imibhobho. Ekubeni iqondo lokushisa lomphunga liphezulu kakhulu kunokushisa kwe-pulp ehanjiswayo, i-steam yokufudumeza iya kumisa i-pulp eseleyo kumbhobho, ngaloo ndlela ichaphazela ukusetyenziswa kombhobho. Kwaye ukuba ukugcinwa kwe-insulation akulungile, umbhobho we-condensate ofudunyezwa ngokufudumeza komphunga wangaphandle uya kuba ngumkhenkce, ude uchaphazele imveliso.

Ngokusekwe kwezi zizathu zingasentla, ii-mill ezininzi zephepha zisebenzisa ukufudumeza kombane okuzenzekelayo kunye neenkqubo zokugquma ukuze kuguqulwe ubugcisa. Le nkqubo yokufudumeza kombane ezenzekelayo kunye nenkqubo yokugquma inokubonelela (0 ~ 60 ℃ ngokuzikhethela) ipulp yonikezelo lobushushu lombhobho, ngokwenjenjalo iphelisa ukomiswa kwepulp okubangelwa liqondo lobushushu eligqithileyo lokufudumeza komphunga kunye nesenzeko somhlwa obangelwa ngumahluko ogqithisileyo wobushushu kwimibhobho, enenzuzo entle kwezoqoqosho. .

Ukuzilawula ngokuzimeleyo iteyiphu yokufudumeza yombane ephantsi sisixhobo sokufudumeza sombane esinokuthi silungelelanise ngokuzenzekelayo ubushushu bokufudumala. Isebenzisa izixhobo zokufudumeza zombane eziphambili kunye nezixhobo zokugquma i-polymer, kwaye ngenkqubo ekhethekileyo yokuvelisa, ifikelela kwiqondo lokushisa elizinzileyo nelilawulekayo. Ukuzilawula kweteyiphu yokufudumeza kombane ephantsi kweqondo eliphantsi kuneenzuzo zokuqalisa kancinci, ukusebenza kakuhle kwememori, izinga eliphantsi lonyaka, kunye nobomi benkonzo ende. Ifaneleke ngokukodwa kwiimeko ezifuna ulawulo oluchanekileyo lobushushu.

Kwinkqubo yokwenza iphepha, imibhobho ye-pulp ixhomekeke kwiqhwa ebusika, echaphazela inkqubo yokuvelisa. Iintambo zokufudumeza zombane ezizilawulayo ezinobushushu obuphantsi zinokufakwa kufutshane nodonga lwangaphandle lombhobho ukubonelela ubushushu obuqhubekayo kumbhobho, ukuhlawulela ukulahleka kobushushu bombhobho, kwaye uqinisekise ukuba i-pulp ayiyi kukhenkceka ngenxa yobushushu obuphantsi ngexesha. uthutho. Ukongezelela, iintambo zokufudumeza zombane ezizilawulayo eziphantsi kweqondo lokushisa ziyakwazi ukulungelelanisa nokulawula ubushushu ngokweemfuno zangempela zokuqinisekisa ukuba i-pulp ihanjiswa ngaphakathi kwinqanaba eliphezulu lobushushu.
