Izithako eziphambili zokungena kwi-basalt fiber

1. Iarhente yokudibanisa

I-arhente yokudibanisa sisixhobo esibalulekileyo sonyango esihlala ixesha elide kwaye sinokumelana nokuguga, sisetyenziswa kakhulu njengesixhobo sokuncedisa kwii-polymer composites, ezinokwahlulwa zibe ziindidi ezine eziphambili ngokwesakhiwo sazo seekhemikhali kunye nokwakheka kwazo: ii-organic complexes, ii-silanes, ii-titanates, kunye nee-aluminium acid compounds. Ukuphuhlisa i-arhente entsha yokudibanisa esebenza kakuhle yenye yeendawo zophando kwi Ifayibha yeglasi intsimi yearhente yokungena. Iarhente yokudibanisa yangaphandle ukongeza kwi-organic interface kunye nokusetyenziswa kwe-inorganic interface coupling, ikwanomsebenzi weqela le-film bonding, ezinye ii-coupling agents nazo zinefuthe lokuthambisa. Uphando lwangoku lwe-coupling agents lugxile ekuphuhliseni ii-coupling agents ezintsha ezinokuphucula i-interfaces zezinto kunye nokuphucula amandla e-bond. Abaphandi baphonononga iindlela ezahlukeneyo zeekhemikhali kunye noyilo olutsha lwezinto ukuphucula ukuhambelana kwe-interfacial, i-affinity kunye namandla e-bond ukuze kufezekiswe ukubopha okungcono kwe-interfacial. Okwangoku ezona zisetyenziswa kakhulu zii-lithane coupling agents kunye nee-titanate coupling agents. I-lithane coupling agent ineendlela ezimbini ezibalulekileyo: okokuqala, inokusabela neqela le-hydroxyl kwi-inorganic material ukwenza i-chemical bond, ngaloo ndlela idibanisa ngempumelelo i-organic kunye ne-inorganic phases kunye nokuphucula ukunamathela kunye ne-affinity ye-interface; okwesibini, i-lithane coupling agent inokunxibelelana ne-long molecular chain kwi-organic material ukuphucula ukuhambelana kunye ne-bond phakathi kwe-polymer kunye ne-inorganic filler, kunye nokuphucula ukusebenza kwezinto. Xa i-titanate coupling agent isabela kunye nee-free protons (H+ ) kwi-interface yezinto ezingaphiliyo, kuyenziwa umaleko we-organic monomolecular. Olu layer lwe-organic monomer lunokwenza umaleko wokugquma kumphezulu we-filler kwaye lusebenzisane ne-polymer, ngaloo ndlela lunyusa ukunamathelana kunye nokubopha phakathi kwe-polymer kunye ne-filler. Ukongezwa kwee-titanate coupling agents kwii-polymers kunokunyusa kakhulu amandla empembelelo yento. Ukongeza, ii-fillers zingongezwa ngama-50% nangaphezulu ngaphandle kokwahlulwa kwesigaba, okugcina ukulingana kunye nokuzinza kwezinto.

2.Izithambisi kunye neearhente ezichasene ne-static

Kwihlabathi liphela xa kusenziwa into engeniswayo, izinto zokuthambisa kunye nezinto ezilwa ne-static zihlala zidityaniswe zibe yinto enye. Izinto zokuthambisa ikakhulu zii-long-chain aliphatic imidazoline okanye i-asidi equlethe iibhondi ezimbini kunye nee-long-chain alcohols monohydroxy esters, ezisetyenziselwa kakhulu ukulawula i-viscosity yesisombululo esingeniswayo, ukunciphisa uxinzelelo lomphezulu waso, ukuze sisasazwe ngokulinganayo kumphezulu wezinto eziphathwayo, ukuphucula indima yokungena. Ii-nanolubricants bezisoloko zingumxholo wophando oshushu kwiminyaka yakutshanje, kwaye zigqunywe nge-coating. I-Basalt Iifayibha azinawo nje kuphela amandla aphezulu okulwa nokuguguleka kodwa zikwafezekisa isiphumo sokunciphisa ukuguguleka. Abaphandi bahlola ukusetyenziswa kwee-nanoparticles kwizithambisi ukuphucula ukuguguleka kunye neempawu zokuguguleka kwezinto. Ngokuxhomekeke kwindima yazo, iithambisi zingahlulwa zibe ziintlobo ezimbini: zangaphakathi nezangaphandle. Izinto ezisetyenziswa kwizithambisi zangaphakathi ikakhulu ziikhompawundi zepolymer, ezifana newax, iipolyolefins, njl.njl., ezinokuhambelana kakuhle, zinokunciphisa ukudibana phakathi kweemolekyuli zepolymer, kwaye ziphucule isenzeko sokuvelisa ubushushu bokuguguleka ngaphakathi kokuguguleka nokuguguleka, ukuze kube nefuthe elingcono ekukhupheni, ekubumbeni ngenaliti kunye nokunye ukucutshungulwa. Ukwakheka kwethambisi yangaphandle ikakhulu ziikhompawundi eziphantsi zeemolekyuli, ezifana nee-esters ze-fatty acid, i-paraffin wax, njl.njl., ezinokuphucula ngempumelelo ukuguguleka phakathi kokuguguleka kunye nomphezulu wezixhobo, zinciphise i-coefficient yokuguguleka kwenkqubo nganye yemveliso, zidlala indima ebalulekileyo ekuxubeni, ekubhaleni, ekubumbeni iswekile, nakwezinye iinkqubo zokubumba. Ii-antistatic agents zinokwahlulwa zibe ziindidi ezimbini: ezingaphiliyo nezingaphiliyo, kwaye indima yazo ephambili kukwenza indlela yokuqhuba kwifilimu engenelayo, ikhuphe itshaja engashukumiyo eveliswa yifayibha ekuvelisweni nasekusetyenzisweni kwenkqubo. Ukongezwa kwee-nanofillers (umz., ii-carbon nanotubes, i-graphene, njl.njl.) kwi-polymer matrix kunokuphucula kakhulu i-conductivity kunye ne-antistatic properties zezinto. Kwiminyaka yakutshanje, abaphandi bazinikele ekuhloleni intsebenziswano phakathi kwee-nanofillers ezahlukeneyo kunye nee-polymer matrices ukuze bafumane ii-antistatic properties ezingcono.

3. Iarhente yokwenza ifilimu

Njengeyona nto ibalulekileyo kwiarhente engena ngaphakathi, iarhente eyenza ifilimu imisela ukusebenza kokucubungula kunye nokusebenza kwemveliso ifayibha yebasaltKwinkqubo yokuvelisa ifayibha ye-basalt, iarhente yokwenza ifilimu inokwenza uqweqwe olufanayo nolusondeleyo kumphezulu wefayibha, iphucule kakhulu ukuhambelana konxibelelwano phakathi kwefayibha kunye nezinto ezisetyenziswa phantsi komhlaba, iphucule amandla okubopha phakathi kobuso, ngaloo ndlela iphucula amandla kunye nokuqina kweefayibha ze-basalt, kodwa ikwathintela ifayibha ekuqhekekeni kwesilika ebhabhayo, ukuqinisekisa ukuthembeka kwefayibha. Ukongeza, iarhente yokwenza ifilimu ikwanika iifayibha ze-basalt ezifana nokukhazimla, ukuthamba, ukugudileyo kunye nezinye iimpawu ezithile kunye nembonakalo. Izinto ezisetyenziswa kakhulu kwi-nanomaterials nazo zisetyenziswe kakhulu kuphando lwee-arhente ezenza ifilimu. Kuye kwaboniswa ukuba ukongezwa kwee-nanoparticles kunokuphucula iipropati ze-physicochemical zee-arhente ezenza ifilimu, ezinje ngokuphucula ukumelana nokukrala, ukumelana nemozulu kunye neepropati zokukhanya.

Iziguquli ze-4.pH

Umlawuli we-pH unokulungisa i-acidity kunye ne-alkalinity ye-infiltrant ukuze ifaneleke ngakumbi ukusebenzisana nayo imicu ye-basaltNgokulungisa i-pH yento engenelayo, iimpawu zetshaja yomphezulu wefayibha zinokutshintshwa ukuze kukhuthazwe amandla okusebenzisana phakathi kwento engenelayo kunye nefayibha, ngaloo ndlela kuphuculwe ukusebenza kokungena kwefayibha. Kuye kwacetyiswa ukuba ii-modulators ze-pH ezisekelwe kwi-nanomaterial zinokubonelela ngokuchanekileyo nangokusebenza kakuhle kwemodyuli. Ukongeza, kukho izifundo kubalawuli be-PH kwiintlobo ezahlukeneyo zefayibha kunye neemeko zokucubungula, ngenjongo yokufumana iziphumo ezingcono zokumanzisa ifayibha kunye nokusebenza kokucubungula.

5. Ezinye izinto

Ii-impregnants zikwaqulathe ii-biocides, ii-emulsifiers, ii-defoamers, njl.njl., ezisetyenziswa kakhulu ukubulala iintsholongwane, ukulawula ukuhambelana kunye nokuzinza kweenxalenye, kunye nokuthintela ukuveliswa kunye nokuqokelelwa kwe-surface foam.
