Ukusukela ekukhuleni kwemizi-mveliso, ukuchitheka kwe-oyile kunye nezingcolisi zezinto eziphilayo kwimizi-mveliso ziye zabeka isoyikiso esibi kwimpilo yabantu, elwandle nakwinkqubo yendalo. Ungcoliseko olubangelwa kukuchitheka kwe-oyile, amanzi amdaka akwimizi-mveliso kunye nokukhutshwa kwezinto eziyingozi kuye kwaqatshelwa njengenye yeengxaki ezinkulu zokusingqongileyo.
Ukongeza kumanzi amdaka aneoyile, ungcoliseko oluphuma kwiindawo zokugcina i-oyile apho idizili nepetroli zigcinwa khona, amanzi amdaka asuka kwiinkqubo zemizi-mveliso enezinto ezineoyile, ungcoliseko oluphuma kumasuntswana ayingozi emoyeni kunye nongcoliseko oluphuma kwisinyithi esiyingozi esiphezu komhlaba naphantsi komhlaba, konke oko kuye kwaba ngumngeni omkhulu kwihlabathi jikelele.
Kwiminyaka yakutshanje, ngokungeniswa kwezinto ezintsha kunye nobuchwepheshe, ukusetyenziswa kwezinto ezinegwebu kunye nezixhobo zesakhiwo esinemingxuma kwicandelo lokuhluza umoya, ukufunxwa kunye nokwahlulwahlulwa kweentwana, ukwahlulwahlulwa kweoyile namanzi kunye nezinye iindlela zokucoca kunye nokwahlulwahlulwa phakathi kwezinto kuye kwaba yindawo ethandwayo, nto leyo enegalelo elibalulekileyo ekusindiseni ingxaki yokusingqongileyo.
Yintoni isipontshi sorhwebo?
Namhlanje, iirobhothi eziphantsi kwamanzi kulindeleke ukuba zenze imisebenzi yokucoca ukuchitheka kwe-oyile enokuthintela ukwanda kwe-oyile kwaye inokususa ngaphezulu kwe-90% yamathontsi eoyile kumanzi amdaka ngaphantsi kwemizuzu elishumi. Isixhobo sokucoca esenza umsebenzi wokuhlula ioli emanzini sisiponji esiqhelekileyo, emva kokubamba ioli kumanzi amdaka, sinokuphathwa nge-solvent ekhupha ioli kwisiponji. Emva kokuba ioli ikhutshiwe kwisipontshi, ingaphinda isetyenziswe izihlandlo ezininzi ngaphandle kokulahlekelwa ukusebenza kwayo.
Ke, yintoni ukuhluza? Ukuhluzwa kukwahlulwa kwezinto eziqinileyo kunye nolwelo ngokusebenzisa into enemingxuma egcina okuqinileyo kunye nolwelo ekudluleni. Kubalulekile ukuqaphela ukuba ulwelo lubandakanya zombini ulwelo kunye neegesi. Izihluzi zinokuba yimichiza, yebhayoloji okanye ngokwasemzimbeni. Ukucoca luphawu olubalulekileyo lwe-foam.
Iisponji zesihluzo zikwaziwa ngokuba ziisponji ezineemesh, iisponji eziqhumayo kunye neesponji ezingangeni uthuli. Iisponji ziyakwazi ukufunxa ubunzima obungaphezulu kwama- 30-100 kwioyile kwaye zinokusetyenziselwa ukucoca ukuchitheka kweoyile ngexabiso eliphantsi nangendlela efanelekileyo ngaphandle kokulimaza ubomi baselwandle. Isponji ingasetyenziswa rhoqo ngokufunxa, ngoko ke isponji itya amanzi kwaye icinezele ioyile.
Iisponji zorhwebo zanamhlanje, ezifana neesponji ze-polyurethane, iisponji ze-polyolefin, iisponji ze-melamine kunye neesponji ze-activated carbon composite, zinomdla kakhulu kwicandelo lokususa ioyile ekrwada emanzini olwandle nakumanzi amdaka emizi-mveliso ngenxa yexabiso lazo eliphantsi, ukwakheka kwazo okune-porosity ephezulu ye-three-dimensional (3D), uxinano oluphantsi, iimpawu ezintle zoomatshini kunye nokusetyenziswa kwakhona okumangalisayo.
Nangona kunjalo, uhlobo lwe-amphiphilic lwezipontshi zorhwebo lunciphisa ukusetyenziswa kwazo kwiinkqubo zonyango zokufunxa ioyile. Ukuze kuphuculwe ukusebenza kwabo kokufunxa ioli, ukuguqulwa kuyadingeka ukuze kufumaneke iziponji ezine-hydrophobic, i-lipophilic kwaye zikhethe ekuhluzeni izinto eziyingozi. Ezi ziponji zintsha, zisebenza kakuhle, nexabiso eliphantsi ziye zabonisa ukusetyenziswa ngamandla kwezorhwebo ekwahlukaneni kwamanzi ne-oyile, ekucoceni umoya, ekutsalweni nasekuhlukaniseni izinto eziyingozi.
Iimpawu zeMetroloji zokucoca amagwebu
Ubuninzi beNet, buchazwa nge-kg/m³, bubunzima bomthamo onikiweyo wemveliso yogwebu. Luphawu oluphambili lomgangatho wamagwebu okucoca. Amagwebu axinanana aphezulu anamandla kwaye azinzile ngaphezu kwamagwebu asezantsi.
- Amandla amakhulu
Amandla acinezelayo esixhobo sogwebu sisixa soxinzelelo olufunekayo ukucinezela izinto ukuya kwipesenti eqingqwe kwangaphambili yobunzima bayo bokuqala (umz. 40%). Amagwebu okucoca anemodyuli yoxinzelelo oluphantsi athambile kwaye athambile ngakumbi kunezo zinamandla oxinzelelo oluphezulu.
- Ukwahlula kwikhefu
Ubude ngexesha lekhefu ngumlinganiselo wesakhono semathiriyeli ukonakala. Kuchongwa kuvavanyo lwe-tensile, apho isampuli yemathiriyeli yoluliwe phantsi kweemeko ezilawulwayo de yaphuke. Ukwandiswa ngexesha lekhefu yisantya sobude apho ukwaphuka kwenzeka kwaye kubonakaliswa njengepesenti yobude besampulu yokuqala.
- Amandla Amandla
Amandla okuqina yenye ipropathi egqitywe kuvavanyo lwe-tensile. Isampulu yemathiriyeli yoluliwe ukuya kukwaphuka. Uxinzelelo apho i-fracture yenzeke khona ngamandla obunzima bezinto eziphathekayo.
- I-PPI ye-foam yokucoca
I-PPI linani lee pores nge-intshi nganye, oko kukuthi, inani lokuvuleka nge-intshi nganye. Izihluzi ze-aquarium kunye ne-aquarium ngamagwebu aneePPI ezahlukeneyo ezichonga inani leeseli ngaphakathi kogwebu. Ngoko ke, ukubala okuphantsi okufana ne-PPI 10 kuthetha ukuba kukho iipores ezimbalwa ngaphakathi kwe-foam kwaye ngoko ke i-bubble pores inkulu kwaye ivulekile, inika indawo eninzi yokudlula amaqhekeza omoya. Kungenjalo, okukhona ubalo lwePPI luphezulu, kokukhona i-foam ixinene, kokukhona ulwelo oluncinci kunye nokunqanda ngakumbi.
Ukusetyenziswa okubalulekileyo kweefoam zokucoca
Izixhobo zokucoca amagwebu kunye ne-porous zizinto eziphambili kunye nezinto eziqhelekileyo ezisetyenziswa kakhulu emoyeni, ulwelo, iikhemikhali, ukhuseleko lokusingqongileyo, amandla, iimoto kunye namanye amashishini kunye nokuphila kwabantu. Izinto zokucoca (izixhobo zokucoca, izixhobo zokucoca, izixhobo zokucoca, izixhobo zokucoca, njl. njl.) zinoluhlu olubanzi kakhulu lwezicelo kwiimoto, i-petrochemical, ukukhuselwa kwendalo kunye namashishini anyukayo nasezantsi, ezibalulekileyo ekusebenzeni okukhuselekileyo nokuthembekileyo kweenkqubo kunye nezixhobo, ukuphuculwa kokusebenza kwemveliso, ukusetyenziswa kwamandla Kukwayinto ephambili yezixhobo zobuchule zokulawula ukungcoliseka komoya kunye neenkqubo zokulawula ukungcoliseka kwamanzi.
Ukuhlelwa kwezinto eziphathekayo zokucoca amagwebu
I-polyurethane foam, i-melamine foam kunye ne-polyolefin enesiponji sekhabhoni esebenzayo zizinto eziqhelekileyo zokucoca kwaye zisetyenziswa ngokubanzi kwiiprojekthi zokucoca imihla ngemihla. Oku kuchasene nobunye ubugcisa obufanayo obuphuhliswayo, obudla ngokubiza, kunzima ukunyusa okanye kufuna ukusetyenziswa kwezinto ezikhethekileyo ezifana ne-carbon nanotubes kunye negraphene. Ukufumaneka ngokubanzi kwesi sixhobo kunye nokulula kwenkqubo yokuvelisa kuthetha ukuba iteknoloji inokunyuswa ngokukhawuleza.
I-Melamine foam
I-ultra-lightweight, i-porous material esetyenziswa kwiimveliso ezahlukeneyo kuquka iipadi zokucoca indlu kunye nemathiriyeli yokugquma. Iziponji ze-melamine ziguqulwa ngokuzintywilisela kwisisombululo esinexabiso elincinci lerabha ye-silicone ebizwa ngokuba yi-PDMS kunye ne-hexane ye-solvent. Ukugquma okucekethekileyo kwale nkqubo kugxotha amanzi kwaye kuvumele i-oyile ukuba ifunxwe kwisiponji, yenze izinto eziphathekayo zibe yi-hydrophobic kunye ne-super lipophilic. Abaphandi baye babonisa ukuba le nto intsha inokususa i-oyile kunye ne-organic chemical contaminants engabonakaliyo (engaxutywanga lula) ngamanzi, njenge-hydrocarbons, i-coolants kunye ne-insulating fluids evela ku-power transformers, iikhompawundi ze-carcinogenic ezibizwa ngokuba yi-PCBs kunye nezibulala-zinambuzane ezithile. Ingaphinda isetyenziswe amatyeli amaninzi kwaye inokusetyenziswa ngokulula ukucoca ukuchitheka kweoyile kunye nokuchitheka kwemichiza yemizi mveliso.
Izixhobo zePorous zisetyenziswa kuluhlu olubanzi lwezicelo kwaye naphi na apho kukho ukuhluzwa zinegalelo.
