Iyo firimu-inogadzira mumiriri ndiyo chikamu chikuru chegirazi fiber infiltrant, kazhinji inoverengera 2% kusvika 15% yechikamu chikuru cheiyo infiltrant formula, basa rayo ndere kubatanidza iyo girazi faibha mumasumbu, mukugadzirwa kwekudzivirira kwefiber, kuitira kuti mabhandi efiber ave nedhigirii rakanaka rekuomarara, agglomeration, kusangana nezvinodiwa zvegirazi fiber process. Iyo inowanzo shandiswa firimu-inogadzira maajenti mugirazi fiber infiltrant formulations mapolymers, anosanganisira epoxy resins, polyurethane, polyester, phenolic resins, modified polypropylene dispersions, kana emulsions. Kuita kwemafirimu ekugadzira maajenti kunonyanya kuenderana nechimiro chemolecular uye huremu hwemamorekuru epolymer. Kune imwechete firimu-inogadzira agent, kuoma kwegirazi fiberinogona kudzorwa nehuremu hwemamorekuru emugadziri wemufirimu, uye mumiriri wekugadzira firimu ane huremu hwemamorekuru huchave nekuoma kwakakwira kwegirazi fiber, iyo yakakodzera kurapwa kwepamusoro.kusimbisa thermoplastic yakachekwa girazi fiber zvigadzirwa, nepo mugadziri wemufirimu ane huremu hwakaderera akakodzera kugadzirwa kweshinda dzinoshandiswa mukupeta nekudhonza. Epoxy resin polymers ine aliphatic hydroxyl, ether, uye epoxy mapoka, uye kune yakasimba kukwezva kwemakemikari pakati pemapoka epolar mu epoxy film-forming agents, saka vane yakanaka adhesion uye bundling mhedzisiro pagirazi fibers;

Pamusoro pezvo, boka re epoxy mu epoxy film-forming agent rinogona kuita neterminal hydroxyl group, terminal carboxyl group, terminal amino group, nemamwe mapoka anoshanda mumainjiniya mapurasitiki akadai sePBT, PET, PA, PC, nezvimwewo, kuvandudza kusimba kwekubatana pakati pegirazi fiber neresin. Polyester film-forming agents ine akawanda ester mapoka, unsaturated chemical bonds, uye hydrophilic mapoka mumaketani makuru, uye kuita kwavo kunoenderana nerudzi rweasidhi nedoro rinoshandiswa mukuumbwa kwepolyester uye chiyero. Kana base resin isiri unsaturated polyester resin, iyo isina unsaturated mbiri bond mupolyester film-forming agent inogona polymerize uye kuyambuka-link nema bond maviri mu base resin kuumba yakasimba kemikari bond kana kupinza kwemuviri, izvo zvinovandudza iyo interfacial bonding simba. Polyester film-forming agents anowanzo kuve neakanakisa kunyorova uye kupinda mukati uye saka anoshandiswa seanonyorovesa ejenti mupultrusion, mhepo, kupfapfaidza, chevron, uye zvimwe zvigadzirwa. Polyurethane film-forming agent molecular chain ine inodzokorodza carbamate chimiro, kuvapo kweaya mapoka epolar kunoita kuti polyurethane kune girazi faibha kuve nekusunga kwakanaka kwazvo, zvikamu zvakapfava uye zvakaomarara zvemusanganiswa wepamusoro elasticity uye abrasion resistance, panguva imwecheteyo, polyurethane iri muboka reisocyanate inogona kupinzwa neamino coupling agent, kusimudzira kemikari inopindirana, kusimudzira kemikari inopindirana neiyo matrix. kuita kwecomposite zvinhuzvigadzirwa.
