Izithako eziyinhloko zokungena kwe-basalt fiber

1. I-ejenti yokuxhumanisa

I-ejenti yokuhlanganisa iyi-ejenti yokwelapha ebalulekile ehlala isikhathi eside futhi imelana nokuguga, esetshenziswa kakhulu njenge-assistant ye-polymer composites, engahlukaniswa ngezigaba ezine ezinkulu ngokuya ngesakhiwo sayo samakhemikhali kanye nokwakheka kwayo: ama-organic complexes, ama-silane, ama-titanate, kanye nama-aluminium acid compounds. Ukuthuthukisa i-ejenti yokuhlanganisa entsha esebenza kahle kakhulu kungenye yemingcele yocwaningo ku- I-Glass Fiber Insimu ye-ejenti yokungena. I-ejenti yokuhlanganisa yangaphandle ngaphezu kokusetshenziswa kwe-interface yezinto eziphilayo kanye nokuhlanganiswa kwe-interface yezinto eziphilayo, nayo inendima yeqembu le-bonding yefilimu, amanye ama-coupling agent nawo anomphumela wokuthambisa ovimbela ukuqina. Ucwaningo lwamanje lwe-coupling agent lugxile ekwakheni ama-coupling agent amasha angenza ngcono i-interface yezinto ezibonakalayo futhi athuthukise amandla e-bond. Abacwaningi bahlola amasu ahlukahlukene amakhemikhali kanye nemiklamo emisha yezinto ezibonakalayo ukuze bathuthukise ukuhambisana kwe-interfacial, i-affinity kanye namandla e-bond ukuze kufezwe ukubopha okungcono kwe-interfacial. Njengamanje ezisetshenziswa kakhulu ama-coupling agent e-lithane kanye nama-coupling agent e-titanate. I-ejenti yokuhlanganisa i-lithane inezindlela ezimbili ezibalulekile: okokuqala, ingasabela neqembu le-hydroxyl ezintweni ezingaphili ukuze yakhe isibopho samakhemikhali, ngaleyo ndlela ihlanganise ngempumelelo izigaba zezinto eziphilayo kanye nezingangaphili ndawonye futhi ithuthukise ukunamathela kanye ne-affinity ye-interface; okwesibili, i-ejenti yokuhlanganisa i-lithane ingasebenzisana neketanga elide lama-molecule ezintweni eziphilayo ukuze ithuthukise ukuhambisana kanye ne-bonding phakathi kwe-polymer kanye ne-inorganic filler, kanye nokuthuthukisa ukusebenza kwezinto. Lapho i-ejenti yokuhlanganisa i-titanate isabela nama-proton amahhala (H+ ) endaweni yokuhlangana kwezinto ezingaphili, kwakheka ungqimba lwe-monomolecular oluphilayo. Lolu ngqimba lwe-monomer oluphilayo lungakha ungqimba olumbozayo ebusweni bokugcwalisa futhi lusebenzisane ne-polymer, ngaleyo ndlela kwandiswe ukunamathelana nokubopha phakathi kwe-polymer kanye nokugcwalisa. Ukwengezwa kwama-ejenti okuhlanganisa i-titanate kuma-polymer kungandisa kakhulu amandla okuthintana kwezinto. Ngaphezu kwalokho, izigcwalisi zingangezwa ngamanani angu-50% noma ngaphezulu ngaphandle kokuhlukaniswa kwesigaba, okugcina ukulingana nokuzinza kwezinto.

2. Izinto zokugcoba kanye nezinto ezilwa nokuqina kwesimo sezulu

Emhlabeni jikelele ekwakhiweni kwe-infiltrant, izinto zokugcoba kanye nezinto ezilwa ne-static zivame ukuhlanganiswa zibe yinto eyodwa. Izinto zokugcoba ikakhulukazi ziyi-long-chain aliphatic imidazoline noma i-asidi equkethe ama-double bond kanye ne-long-chain alcohols monohydroxy esters, ezisetshenziswa kakhulu ukulawula i-viscosity yesisombululo se-infiltrant, ukunciphisa ukucindezeleka kobuso bayo, ukuze isatshalaliswe ngokulinganayo ebusweni bezinto eziphathwe kahle, ukuthuthukisa indima yokungena. Izinto zokugcoba ezincane bezilokhu ziyisihloko socwaningo esishisayo eminyakeni yamuva, futhi zimbozwe. I-Basalt Imicu ayigcini nje ngokuba nokusebenza okuphezulu kokulwa nokuguguleka kodwa futhi ifinyelela umphumela wokunciphisa ukuguguleka. Abacwaningi bahlola ukusetshenziswa kwama-nanoparticles kuma-lubricant ukuze kuthuthukiswe ukuguguleka kanye nezakhiwo zokuguguleka kwezinto. Kuye ngendima yazo, ama-lubricant angahlukaniswa ngezinhlobo ezimbili: zangaphakathi nezangaphandle. Izingxenye zama-lubricant angaphakathi ikakhulukazi ama-polymer compounds, njenge-wax, ama-polyolefin, njll., anokuhambisana okuhle, anganciphisa ukuhlangana phakathi kwama-molecule e-polymer, futhi athuthukise isimo sokukhiqiza ukushisa kokuguguleka ngaphakathi kokuguguleka nokuncibilika, ukuze kube nomphumela ongcono ekukhipheni, ekubunjweni komjovo kanye nokunye ukucubungula. Ukwakheka kwe-lubricant yangaphandle ikakhulukazi ama-molecule aphansi, njenge-fatty acid esters, i-paraffin wax, njll., okungathuthukisa ngempumelelo ukuguguleka phakathi kokuncibilika kanye nobuso bemishini, kunciphise i-friction coefficient yenqubo ngayinye yokukhiqiza, kudlala indima ebalulekile ekuxubeni, ekubhaleni, ekubunjweni koshukela, nakwezinye izinqubo zokubumba. Ama-antistatic agents angahlukaniswa ngezigaba ezimbili: angaphili kanye nawaphilayo, futhi indima yawo eyinhloko ukwakha indlela yokuqhuba efilimini engenayo, ikhipha ishaja engaguquki ekhiqizwa yi-fiber ekukhiqizweni nasekusetshenzisweni kwenqubo. Ukwengezwa kwama-nanofillers (isb., ama-carbon nanotubes, i-graphene, njll.) ku-polymer matrix kungathuthukisa kakhulu ukuguquguquka kanye nezakhiwo ezingaguquki zezinto. Eminyakeni yamuva nje, abacwaningi bebezinikele ekuhloleni ukusebenzisana phakathi kwama-nanofillers ahlukene kanye nama-polymer matrices ukuze bathole izakhiwo ezingcono ezingaguquki.

3. I-ejenti yokwakha amafilimu

Njengengxenye ebaluleke kakhulu ku-ejenti engena ngaphakathi, i-ejenti eyakha ifilimu inquma ukusebenza kokucubungula kanye nokusebenza komkhiqizo we- i-basalt fiber. Enqubweni yokukhiqiza i-basalt fiber, i-ejenti eyakha ifilimu ingakha ungqimba olufanayo nolusondelene ebusweni be-fiber, ithuthukise kakhulu ukuhambisana kokuxhumana phakathi kwe-fiber nezinto ezisetshenziswayo, ithuthukise amandla okubopha okusebenzisana, ngaleyo ndlela ithuthukise amandla nokuqina kwe-basalt fibers, kodwa futhi ivimbele i-fiber ekuqhekekeni kwesilika esindizayo, ukuqinisekisa ubuqotho be-fiber. Ngaphezu kwalokho, i-ejenti eyakha ifilimu inganikeza ne-basalt fibers ezifana nokucwebezela, ukuthamba, ukushelela kanye nezinye izakhiwo ezithile kanye nokubukeka. Izinto ezisetshenziswa kakhulu zisetshenziswe kabanzi ocwaningweni lwe-ejenti eyakha ifilimu. Kuye kwaboniswa ukuthi ukwengezwa kwe-nanoparticles kungathuthukisa izakhiwo ze-physicochemical ze-ejenti eyakha ifilimu, njengokuthuthukisa ukumelana nokuklwebheka, ukuqina kwesimo sezulu kanye nezakhiwo zokukhanya.

Iziguquli ze-4.pH

Umlawuli we-pH angalungisa ubumuncu kanye ne-alkalinity ye-infiltrant ukuze ifaneleke kakhulu ekusebenzisaneni ne- imicu ye-basaltNgokulungisa i-pH yento engenela ngaphakathi, izici zokushaja kobuso befayibha zingashintshwa ukuze kukhuthazwe amandla okusebenzisana phakathi kwento engenela ngaphakathi nefayibha, ngaleyo ndlela kuthuthukiswe ukusebenza kokungena kwefayibha. Kuye kwaphakanyiswa ukuthi ama-modulator e-pH asekelwe ezintweni ezibonakalayo anganikeza ukunemba nokusebenza kahle kokuguquguquka okuphezulu. Ngaphezu kwalokho, kunezifundo kubalawuli be-PH bezinhlobo ezahlukene zefayibha kanye nezimo zokucubungula, ngenhloso yokuthola imiphumela engcono yokumanzisa ifayibha kanye nokusebenza kokucubungula.

5. Ezinye izingxenye

Ama-impregnant aqukethe nama-biocides, ama-emulsifier, ama-defoamers, njll., asetshenziswa kakhulu ukubulala amagciwane, ukulawula ukuhambisana nokuqina kwezingxenye, nokuvimbela ukukhiqizwa nokuqongelela kwe-surface foam.
