7. Xa iyeza lithe lachukumisa amehlo ngempazamo, hlambulula ngamanzi kuqala. Ukuba uzive ungaphilanga, nceda udibane nogqirha kwangethuba.
3. Ububanzi besicelo:
Ifanelekile ukucima imililo yeKlasi A okanye imililo yeKlasi A kunye neKlasi B. Isetyenziswa kakhulu ekuthinteleni nasekuhlanguleni imililo kumashishini emizi-mveliso kunye nemigodi, kwiilori zomlilo, kwizikhululo zeenqwelo-moya, kwizikhululo zepetroli, kwiinqanawa zokuthutha ioli, kumasimi eoyile, kwiindawo zokucoca ioli, nakwiindawo zokugcina ioli.
Isixhobo sokucima umlilo esisekelwe emanzini (uhlobo lwejeli yepolymer)
1. Isishwankathelo semveliso
Isithako sokucima umlilo sejeli yepolymer sikwimo yomgubo omhlophe, kwaye amasuntswana amancinci anamandla amakhulu okucima umlilo emanzini. Ayincinci nje kuphela ngomlinganiselo, kodwa kulula ukuyisebenzisa. Ubushushu bungaphantsi kwama-500℃ kwaye buzinzile kakhulu kwaye abudli izixhobo zokucima umlilo. Ke ngoko, ijeli ingalungiswa ngaphambi kokusetyenziswa, okanye ingalungiswa kwaye igcinwe kwitanki yamanzi ukuze isetyenziswe kamva.
Isixhobo sokucima umlilo sejeli yepolymer sisixhobo esongezelelweyo sokucima umlilo esinokufunxa amanzi amaninzi, ixesha elide lokutshixa amanzi, ukumelana nomlilo okuphezulu, ukunamathela okuqinileyo, ukhuseleko lokusingqongileyo, asinabungozi, kulula ukusisebenzisa, kunye nokuthuthwa nokugcinwa okulula. Imveliso ayinakutshixa amanzi amaninzi kuphela, kodwa ikwapholisa ngokukhawuleza izinto ezitshayo. Ingenza umaleko wokugquma we-hydrogel phezu komphezulu wento ukuze yahlukanise umoya, ngelixa ithintela ukusasazeka kweegesi ezinobuthi neziyingozi. Umaleko wokugquma wejeli unomlinganiselo omkhulu wokufunxa ngokukhawuleza izinto ezitshayo. Oku kunciphisa ubushushu bomphezulu wezinto ezitshayo kwaye kufezekisa injongo yokulawula ukusasazeka komlilo kunye nokucima umlilo ngokukhawuleza nangokufanelekileyo.
Ukusebenzisa ijeli ukucima umlilo kuyasebenza, kunobuhlobo nokusingqongileyo, kwaye kuyonga amanzi. Ngokuphathelele amandla okucima umlilo, ilori yomlilo exhotyiswe ngejeli ilingana neelori zomlilo ezingama-20 ezixhotyiswe ngamanzi. Imigaqo kunye neendlela zokulwa nomlilo ziyafana nezo zamanzi. Xa ijeli icima imililo yasezidolophini yeClass A, isiphumo sayo sokumelana nomlilo singaphezulu kwezihlandlo ezi-6 kunesamanzi; xa icima imililo yamahlathi neyamahlathi, isiphumo sayo sokumelana nomlilo singaphezulu kwezihlandlo ezili-10 kunesamanzi.
2. Ububanzi besicelo
Isithako sokucima umlilo sejeli yepolymer esine-0.2% ukuya kwi-0.4% yesithako sokucima umlilo se-polymer singenza i-arhente yokucima umlilo yejeli kwimizuzu emi-3. Sitshiza i-arhente yokucima umlilo yejeli ngokulinganayo kwizinto ezivuthayo eziqinileyo, kwaye emva koko ifilimu yejeli etyebileyo inokwenziwa kumphezulu wento ngoko nangoko. Singakwazi ukwahlukanisa umoya, sipholise umphezulu wento, sidle ubushushu obuninzi, kwaye sidlale indima entle ekuthinteleni umlilo kunye nokucima umlilo. Isiphumo sinokucima ngempumelelo imililo yeClass A (izinto ezivuthayo eziqinileyo) emahlathini, emadlelweni nasezidolophini. I-carbon dioxide kunye nomphunga wamanzi oveliswa kukutsha kwe-resin efunxa amanzi azitshi kwaye azinatyhefu.
Ezintathu, iimpawu zemveliso
Ukonga amanzi-Izinga lokufunxwa kwamanzi kwesongezo sokucima umlilo sejeli yepolymer linokufikelela kwizihlandlo ezingama-400-750, nto leyo enokuphucula ngempumelelo izinga lokusetyenziswa kwamanzi. Kwindawo yomlilo, amanzi amancinci anokusetyenziswa ukulawula ukusasazeka komlilo nokucima umlilo ngokukhawuleza.
Isixhobo sokucima umlilo esisebenzayo-I-Hydrogel sinamathela ngaphezu kwezihlandlo ezi-5 zamanzi xa sicinywa imililo yeClass A kunye nemililo yamahlathi kunye neyamahlathi; isiphumo saso sokungacimi umlilo sinamathela ngaphezu kwezihlandlo ezi-6 zamanzi. Xa sicinywa imililo yamahlathi kunye neyamahlathi, isiphumo saso sokungacimi umlilo sinamathela ngaphezu kwezihlandlo ezili-10 zamanzi. Ngenxa yezinto ezahlukeneyo zezinto eziqinileyo, ukunamathela kwaso kwahlukile.
Ukhuseleko lokusingqongileyo-Emva komlilo, i-hydrogel eseleyo yokucima umlilo kwindawo ayinangcoliseko kwindalo kwaye inefuthe lokugcina umswakama emhlabeni. Ingaguqulwa ngokwendalo ibe ngamanzi kunye negesi yekhabhoni-dayoksayikloji kwixesha elithile; ayizukubangela ungcoliseko kwimithombo yamanzi nakwindalo.

Umlinganiselo wokuxuba wezixhobo ezi-7 kwitoni e-1 yamanzi, wongeza iikhilogram ezi-2 ukuya kwezi-3 zezongezo zokucima umlilo zejeli yepolymer (ezonyukileyo okanye ezinciphileyo ngokomgangatho wamanzi owahlukileyo)
Ezintlanu, isicelo semveliso
Iarhente yokucima umlilo yefoam enganyibilikiyo emanzini enyibilikayo
Imvelaphi yemveliso:
Kwiminyaka yakutshanje, iingozi ezifana nemililo kunye nokuqhuma kwizityalo zeekhemikhali ziye zenzeka rhoqo; ngakumbi, abanye abavelisi beemveliso zeekhemikhali ze-polar solvent banenani elikhulu lezinto ezivuthayo nezitshayo, iigesi ezitshayo ezinyibilikayo, kunye nezinto eziqinileyo ezitshayo, izixhobo zemveliso ezintsonkothileyo, iinethiwekhi zemibhobho ezinqumlayo, kunye namaqondo obushushu aphezulu. Kukho izikhongozeli ezininzi kunye nezixhobo ezikwimeko yoxinzelelo oluphezulu, kwaye ingozi yomlilo inkulu. Nje ukuba umlilo okanye ukuqhuma kubangele ukutsha, kuya kwenza ukutsha okuzinzileyo. Emva kokuqhuma, ioyile iphuma phezulu kwetanki okanye iyaqhekeka kwaye ioyile iphuma ngenxa yokufuduka komzimba wetanki inokubangela lula umlilo wokuhamba komhlaba.
Ngokubanzi, ifoam yeKlasi A okanye yeKlasi B isetyenziselwa ukucima umlilo kwindawo yomlilo. Nangona kunjalo, xa umlilo uvela ngezinyibilikisi ze-polar ezifana notywala, ipeyinti, utywala, i-ester, i-ether, i-aldehyde, i-ketone, kunye ne-amine, kunye nezinto ezinyibilikayo emanzini. Ukukhetha ngokuchanekileyo kunye nokusetyenziswa kwee-arhente zokucima umlilo sisiseko sokulwa nomlilo ngokufanelekileyo. Ngenxa yokuba izinyibilikisi ze-polar zinokuxutywa namanzi, ifoam eqhelekileyo iyatshatyalaliswa ngeli xesha le nkqubo kwaye ilahlekelwe yimpembelelo yayo efanelekileyo. Nangona kunjalo, ukongezwa kwezithako ezifana neepolymers ze-polysaccharide eziphezulu kwifoam enganyangekiyo ngotywala kunokumelana nokunyibilika kwezinyibilikisi zotywala kwaye kuqhubeke nokusebenzisa impembelelo yazo kwi-alcohols. Ke ngoko, utywala, ipeyinti, utywala, i-ester, i-ester, i-aldehyde, i-ketone, i-amine kunye nezinye izinyibilikisi ze-polar kunye nezinto ezinyibilikayo ngamanzi kufuneka zisebenzise ifoam enganyangekiyo ngotywala xa umlilo uvela.
1. Isishwankathelo semveliso
Iarhente yokucima umlilo ye-foam elwa ne-solvent foam elwa ne-solvent isetyenziswa kakhulu kwiinkampani ezinkulu zeekhemikhali, kwiinkampani ze-petrochemical, kwiinkampani ze-chemical fiber, kwizityalo ze-solvent, kwiindawo zokugcina iimveliso zeekhemikhali kunye namasimi eoyile, kwiindawo zokugcina ioyile, kwiinqanawa, kwii-hangars, kwiigaraji nakwezinye iiyunithi kunye neendawo apho kulula ukuvuza khona ipetroli. Isetyenziselwa ukucima umlilo weoyile kubushushu obuphezulu, kwaye ifanelekile kwi-"submerged jet" yokucima umlilo. Ineempawu zearhente yokucima umlilo ye-foam elwa ne-foam elwa nefilimu yamanzi yokucima ioyile kunye neemveliso zepetroleum kunye nezinye izinto ezinganyibilikiyo emanzini. Ikwanayo ne-firewall egqwesileyo yolwelo olunokutsha olunyibilikayo emanzini olufana neealcohols, ii-esters, ii-ethers, ii-aldehydes, ii-ketones, ii-amines, ii-alcohols, njl.njl. Ingasetyenziswa njengearhente yokumanzisa neyokungena ukucima imililo yeKlasi A, enefuthe lokucima umlilo jikelele.
2. Ububanzi besicelo
Iiarhente zokucima umlilo zefoam ezimelana nokunyibilika kwamanzi ezibumba ifilimu ye-B zisetyenziswa kakhulu ekulweni neentlobo ezahlukeneyo zemililo ye-B. Ukusebenza kokucima umlilo kuneempawu zeoyile yokucima kunye neemveliso zepetroliyam zeearhente zokucima umlilo zefoam ezibumba ifilimu ye-aqueous, kunye neearhente zokucima umlilo zefoam ezimelana notywala. Iimpawu zomlilo ze-polar solvents kunye nezinto ezinyibilikayo emanzini ezifana neepeyinti, ii-alcohols, ii-esters, ii-ethers, ii-aldehydes, ii-ketones, ii-amines, njl. Ingenza lula ukusindiswa kwemililo ye-B engaziwayo okanye exutyiweyo ngeeoyile kunye nezinyibilikisi ze-polar, ngoko ke ineempawu zokucima umlilo jikelele.
