I-basalt fiber infiltrant izithako eziphambili

1.I-arhente yokudibanisa

I-agent yokudibanisa i-arhente yonyango ebalulekileyo kunye nokuqina okulungileyo kunye nokuchasana nokuguga, ngokukodwa isetyenziswe njengencedisi kwii-polymer composites, ezinokuthi zohlulwe zibe ziindidi ezine ezinkulu ngokwemichiza yayo kunye nokubunjwa kwayo: i-organic complexes, i-silanes, i-titanates, kunye ne-aluminium acid compounds. Ukuphuhlisa i-arhente entsha yokudibanisa esebenzayo yenye yemida yophando kwi IFayibha yeglasi indawo yearhente yokungena. I-arhente yokudibanisa yamazwe angaphandle ukongeza kujongano lwendalo kunye nokusetyenziswa konxibelelwano lwe-inorganic interface, ikwanendima yeqela lokudibanisa ifilimu, ezinye iiarhente zokudityaniswa zinefuthe lokuthambisa i-antistatic. Uphando lwangoku lwe-ejenti yokudibanisa ijolise ekuphuhliseni ii-arhente ezintsha zokudibanisa ezinokwandisa ujongano lwemathiriyeli kunye nokwandisa amandla ebhondi. Abaphandi baphonononga amaqhinga ahlukeneyo ekhemikhali kunye noyilo lwemathiriyeli emitsha yokuphucula ukuhambelana kobuso, umanyano kunye namandla okudibanisa ukufezekisa ukudibanisa okungcono kobuso. Okwangoku ezona zixhobo zisetyenziswa kakhulu zii-agent zokudibanisa i-lithane kunye ne-titanate coupling agents. I-agent yokudibanisa i-lithane ineendlela ezimbini ezibalulekileyo: okokuqala, inokusabela kunye neqela le-hydroxyl kwizinto ezingabonakaliyo ukwenza i-chemical bond, ngaloo ndlela idibanisa ngokufanelekileyo izigaba eziphilayo kunye ne-inorganic kunye nokuphucula ukubambelela kunye nokudibanisa kwe-interface; okwesibini, i-agent yokudibanisa i-lithane inokusebenzisana nekhonkco elide le-molecular kwi-organic material ukunyusa ukuhambelana kunye nokudibanisa phakathi kwe-polymer kunye ne-inorganic filler, kunye nokuphucula ukusebenza kwezinto. Xa i-agent ye-titanate coupling isabela kunye neeproton zamahhala (H +) kwi-interface yezinto ezingaphiliyo, i-organic monomolecular layer yenziwa. Lo maleko we-organic monomer unokwenza umaleko wokugubungela kumphezulu wokuzalisa kwaye unxibelelane nepolymer, ngaloo ndlela ukwandisa ukunamathela kunye nokudibanisa phakathi kwepolymer kunye nefayili. Ukongezwa kwe-titanate coupling agents kwiipolymers kunokunyusa kakhulu amandla empembelelo yezinto. Ukongezelela, iifayili zinokuthi zongezwa kwiimali ze-50% okanye ngaphezulu ngaphandle kokuhlukana kwesigaba, esigcina i-homogeneity kunye nokuzinza kwezinto.

2.I-Lubricants kunye ne-antistatic agents

Ngamazwe ngamazwe ekuqulunqweni kwe-infiltrant, i-lubricants kunye ne-antistatic agents zihlala zidibaniswa zibe enye. Izithambisi ubukhulu becala imidazoline chain aliphatic okanye iasidi equlathe iibhondi kabini kunye chain alkoholi elide monohydroxy esters, ikakhulu esetyenziselwa ukulawula viscosity yesisombululo infiltrant, ukunciphisa ukuxinezeleka yayo phezu komhlaba, ukuze isasazwe ngokufanayo kumphezulu wezinto ephathwayo, ukwandisa indima yokungena. I-Nanolubricants ibe sisihloko sophando esishushu kwiminyaka yakutshanje, kwaye igqunywe Ibasalt iifibers azinayo nje ukusebenza okuphezulu kokuchasana nokunxiba kodwa zikwaphumeza isiphumo sokunciphisa ukungqubana. Abaphandi baphonononga ukusetyenziswa kwe-nanoparticles kwii-lubricants ukuphucula ukungqubuzana kunye nokugqoka iimpawu zezinto eziphathekayo. Ngokuxhomekeke kwindima yabo, izithambiso zingahlelwa zibe ziindidi ezimbini: ngaphakathi nangaphandle. Amacandelo ezithambisi zangaphakathi ubukhulu becala iikhompawundi polymer, ezifana wax, polyolefins, njl, ezinokuhambelana kakuhle, kunokunciphisa ukudityaniswa phakathi iimolekyuli polymer, nokuphucula isenzeko ubushushu ukungqubana phakathi inyibilika kunye nokunyibilika fluidity, ukuze kube nefuthe elingcono extrusion, naliti ukubumba kunye nezinye processing. Ukubunjwa kwe-lubricant yangaphandle ubukhulu becala iikhompawundi ze-molekyuli eziphantsi, ezifana ne-fatty acid esters, i-wax yeparafini, njl., Enokuphucula ngokufanelekileyo ukungqubana phakathi kokunyibilika kunye nomphezulu wesixhobo, ukunciphisa i-coefficient ye-friction yenkqubo nganye yokuvelisa, idlala indima ebalulekileyo ekuxubeni, i-calendering, ukubumba iswekile, kunye nezinye iinkqubo zokubumba. I-Antistatic agents zinokwahlulwa zibe ziindidi ezimbini: i-inorganic and organic, kwaye indima yazo ephambili kukwenza indlela yokuqhubela phambili kwifilimu engena ngaphakathi, ukukhulula intlawulo ye-static eyenziwa yifiber kwimveliso kunye nokusetyenziswa kwenkqubo. Ukongezwa kwe-nanofillers (umzekelo, i-carbon nanotubes, i-graphene, njl.) kwi-matrix ye-polymer inokuphucula kakhulu i-conductivity kunye ne-antistatic properties. Kwiminyaka yakutshanje, abaphandi bazinikele ekuphononongeni intsebenziswano phakathi kwee-nanofillers ezahlukeneyo kunye ne-polymer matrices ukufumana iipropathi ezingcono ze-antistatic.

3.Iarhente yokwenza ifilimu

Njengelona candelo libaluleke kakhulu kwi-arhente yokungena, i-arhente yokwenza ifilimu imisela ukusebenza kokucubungula kunye nokusebenza kwemveliso. i-basalt fiber. Kwinkqubo yokuvelisa ifayibha ye-basalt, i-agent eyenza ifilimu inokwenza iyunifomu kwaye ivale i-coat kumphezulu wefiber, iphucule kakhulu ukuhambelana kojongano phakathi kwefiber kunye ne-substrate, iphucule amandla okudibanisa ubuso, ngaloo ndlela iphucula amandla kunye nokuqina kwe-basalt fibers, kodwa nokukhusela ifayibha ekuqhekekeni kwe-silk ephaphazelayo, ukuqinisekisa ukunyaniseka kwefayibha. Ukongezelela, i-agent-forming agent inokunika i-basalt fibers efana ne-gloss, i-soft, i-smooth kunye nezinye iimpawu ezithile kunye nokubonakala. I-Nanomatadium nayo isetyenziswe ngokubanzi kuphando lwe-arhente yokwenza ifilimu. Kuye kwaboniswa ukuba ukongezwa kwe-nanoparticles kunokuphucula iimpawu ze-physicochemical ze-film-forming agents, ezifana nokuphucula ukuxhatshazwa kwe-abrasion, isimo sezulu kunye neempawu ezibonakalayo.

Izilungiso ze-4.pH

Umlawuli we-pH unokulungelelanisa ubumuncu kunye ne-alkalinity yomntu ongenayo ukuze ayenze ifaneleke ngakumbi ukusebenzisana nayo. imicu yebasalt. Ngokulungelelanisa i-pH ye-infiltrant, iimpawu zentlawulo ze-fiber surface zingatshintshwa ukuze kukhuthazwe amandla okusebenzisana phakathi kwe-infiltrant kunye nefiber, ngaloo ndlela kuphuculwe ukusebenza kokungena kwefiber. Kuye kwacetyiswa ukuba i-nanomaterial-based modulators ye-pH inokubonelela ngokuchaneka okuphezulu kunye nokusebenza kakuhle. Ukongeza, kukho izifundo kubalawuli be-PH kwiintlobo zefayibha ezahlukeneyo kunye neemeko zokusetyenzwa, ngombono wokufumana iziphumo ezingcono zokumanzisa ifayibha kunye nokusebenza kokusebenza.

5.Amanye amacandelo

I-Impregnants iqulethe i-biocides, i-emulsifiers, i-defoamers, njl., ezisetyenziselwa ukubulala i-microorganisms, ukulawula ukuhambelana kunye nokuzinza kwamacandelo, kunye nokuthintela ukuveliswa kunye nokuqokelela kwe-foam yomhlaba.
