Faibha yegirazi ndeimwe yezvinhu zvikuru zvemasiringi efiberglass uye mapaneru efiberglass anobata ruzha.magirazi egiraziKugadzira gypsum boards kunonyanya kukosha pakuwedzera simba remapaneru. Simba remasiringi efiberglass nemapaneru anotora ruzha zvinokanganiswawo zvakananga nehunhu hwemafiber egirazi. Nhasi tichataura nezve fiberglass.
Chiifiberglass:
Fiber yegirazi chinhu chisina kugadzirwa nesimbi chinoshanda zvakanaka. Kune mhando dzakawanda. Zvakanakira zvacho ipurasitiki yakanaka, inodzivirira kupisa zvakanyanya, inodzivirira ngura zvakanaka uye ine simba rakawanda remuchina.
Magadzirirwo egirazi faibha:
Chiratidzo chekutanga:mushonga unoshanda pamusoro unoshandiswa pakudhirowa fiber yegirazi. Mushonga unoshanda pamusoro unozivikanwawo semushonga wekunyorovesa, mushonga wekunyorovesa unonyanya kukonzera kubatana uye kugadzira firimu, uye kunewo mamwe mafuta, ma antioxidants, ma emulsifier, ma antistatic agents, nezvimwewo. Mhando dzezvimwe zvinowedzera zvine simba guru pafiber yegirazi, saka paunenge uchisarudza fiber yegirazi, sarudza fiber yegirazi yakakodzera zvichienderana nezvinodiwa zvechinhu chepakutanga uye chigadzirwa chapera.
Chiratidzo chechipiri:dhayamita ye monofilament. Zvakambotaurwa kuti kureba kwegirazi remachira kwakakosha kunongoenderana nesimba rekuchekwa uye dhayamita ye filament. Panyaya yedzidziso, dhayamita ye filament idiki, zvinoita kuti michina uye chitarisiko chepamusoro chechinhu chive nani. Parizvino, dhayamita yegirazi remumba inowanzova 10μm ne13μm.
Kupatsanura kwemagirazi egirazi
Kazhinji, inogona kupatsanurwa zvichienderana nekuumbwa kwezvinhu zvakagadzirwa negirazi, dhayamita yemonofilament, chitarisiko chefiber, nzira yekugadzira uye hunhu hwefiber.
Zvichienderana nekuumbwa kwezvinhu zvegirazi, inonyanya kushandiswa pakupatsanura magirazi anoenderera mberi.
Kazhinji inosiyaniswa nehuwandu hwema alkali metal oxides akasiyana, uye alkali metal oxides anowanzo kureva sodium oxide ne potassium oxide. Mugirazi raw material, inounzwa ne soda ash, Glauber's salt, feldspar nezvimwe zvinhu. Alkali metal oxide ndeimwe yezvikamu zvikuru zvegirazi rakajairika, uye basa rayo guru nderekuderedza kunyunguduka kwegirazi. Zvisinei, kana huwandu hwe alkali metal oxides mugirazi hwakakwira, kugadzikana kwayo kwemakemikari, hunhu hwemagetsi hwekudzivirira uye simba zvinoderera zvinoenderana. Naizvozvo, kune magirazi fibers ane mashandisirwo akasiyana, zvikamu zvegirazi zvine alkali zviri mukati zvinofanirwa kushandiswa. Naizvozvo, huwandu hwe alkali hwezvikamu zvegirazi fibers hunowanzo shandiswa sechiratidzo chekusiyanisa magirazi fibers anoenderera mberi nezvinangwa zvakasiyana. Zvichienderana nehuwandu hwe alkali mukugadzirwa kwegirazi, ma fibers anoenderera mberi anogona kukamurwa kuita marudzi anotevera:
Faibha isina alkali (inozivikanwa segirazi reE):Kuwanda kweR2O kuri pasi pe0.8%, inova chikamu chealuminoborosilicate. Kugadzikana kwayo kwemakemikari, hunhu hwayo hwekuputira magetsi, uye simba rayo zvakanaka kwazvo. Inonyanya kushandiswa sezvinhu zvinoputira magetsi, zvinhu zvinosimbisa zvakagadzirwa nepurasitiki yakasimbiswa nefiber yegirazi uye tambo yetayi.
Pakati nepakati-alkaligirazifaibha:Zviri mukati meR2O i11.9%-16.4%. Ichi chikamu che sodium calcium silicate. Nekuda kwehuwandu hwayo hwakawanda hwe alkali, haigone kushandiswa sechinhu chekudzivirira magetsi, asi kugadzikana kwayo kwemakemikari uye simba zvichiri zvakanaka. Inowanzo shandiswa sejira re latex, jira re checkered, jira re acid filter, jira re window screen, nezvimwewo. Inogona zvakare kushandiswa seFRP reinforcement material isina zvinodiwa zvakanyanya pamagetsi uye simba rayo. Iyi fiber inodhura zvishoma uye ine mashandisirwo akasiyana-siyana.
Fiber dzine alkali yakawanda:Zvikamu zvegirazi zvine huwandu hweR2O hwakaenzana kana kupfuura 15%. Zvakadai semagirazi anotorwa kubva mugirazi rakapwanyika, girazi rebhodhoro rakapwanyika, nezvimwewo, zviri muchikamu ichi. Zvinogona kushandiswa sekuparadzanisa mabhatiri, jira rekuputira mapaipi uye jira remachira nezvimwe zvinhu zvisingapindi mvura uye zvisingapindi hunyoro.
Magirazi akakosha: dzakadai semagirazi ane simba guru anoumbwa nemagirazi e magnesium-aluminum-silicon ternary akachena, magirazi e magnesium-aluminum-silicon ane simba guru uye elastic akasimba; magirazi e silicon-aluminum-calcium-magnesium anodzivirira makemikari; magirazi ane aluminium; magirazi ane silica yakawanda; magirazi e quartz, nezvimwewo.
Kupatsanurwa nedhayamita yemonofilament
Filament yegirazi ine simbi yakaita sedenderedzwa, saka ukobvu hwayo hunogona kuratidzwa mudhayamita. Kazhinji, zvichienderana nehuwandu hwedhayamita, shinda dzegirazi dzakakweverwa dzinokamurwa kuita mhando dzakasiyana (dhayamita yacho iri muum):
Faibha isina kuchena:dhayamita yayo ye monofilament inowanzo kuve 30um
Faibha huru:dhayamita yayo ye monofilament yakakura kupfuura 20um;
Faibha yepakati:dhayamita yemonofilament 10-20um
Faibha yepamusoro:(inozivikanwawo sefiber yejira) dhayamita yayo yemonofilament i3-10um. Fibre dzegirazi dzine monofilament dhayamita iri pasi pe4um dzinonziwo ultrafine fibers.
Madhayamita akasiyana emonofilaments haana hunhu hwakasiyana hwemafiber chete, asiwo anokanganisa maitiro ekugadzira, kubuda uye mutengo wemafiber. Kazhinji, 5-10um fiber inoshandiswa kugadzira zvigadzirwa zvemachira, uye 10-14um fiber inowanzo kukodzeraGirazi reFiberglasskufamba-famba, jira risina kurukwa,fiberglasszvakatemwatambometi, nezvimwewo.
Kupatsanurwa nechitarisiko chefiber
Kuonekwa kweshinda dzegirazi, kureva chimiro chadzo nehurefu hwadzo, zvinoenderana nekuti dzinogadzirwa sei, pamwe nekushandiswa kwadzo. Dzinogona kukamurwa kuita:
Faibha inoenderera mberi (inozivikanwawo sefaibha yemachira):Mupfungwa, fiber inoenderera mberi ifiber isingaperi isingaperi, inonyanya kukwezvwa nenzira ye bushing. Mushure mekugadzirwa kwemachira, inogona kugadzirwa kuita shinda yegirazi, tambo, jira, bhandi, isina kumonyoroka. Kufamba-famba nezvimwe zvigadzirwa.
Faibha yakareba:Kureba kwayo kwakaganhurirwa, kazhinji 300-500mm, asi dzimwe nguva inogona kureba, senge shinda refu dzakasvibiswa dziri mumachira. Semuenzaniso, donje refu rinogadzirwa nenzira yekuputira nemhepo rinoreba mamirimita mashoma chete mushure mekunge rapwanywa kuita shinda dzemakushe. Kune zvimwe zvigadzirwa zvakaita senzira yetsvimbo shinda dzemakushe uye shinda dzekutanga, izvo zvese zvinogadzirwa kuita shinda dzemakushe kana machira.
Makushe egirazi:Ifiber yegirazi ine urefu hwakatarwa, uye fiber yayo ipfupi, kazhinji iri pasi pe150mm kana pfupi. Yakapfava muchimiro, yakafanana nedonje, saka inonziwo donje pfupi. Inonyanya kushandiswa kuchengetedza kupisa uye kupinza ruzha. Pamusoro pezvo, kune fiber dzakachekwa, fiber dzisina chinhu, upfu hwegirazi uye fiber dzakakuyiwa.
Kupatsanurwa zvichienderana ne faibha
Iyi imhando itsva yegirazi fiber yakagadzirwa patsva kuti ienderane nezvinodiwa zvekushandisa. Fiber yacho pachayo ine zvimwe zvinhu zvakakosha uye zvakanaka. Inogona kukamurwa kuita: fiber yegirazi yakasimba kwazvo; high-modulusgirazi faibha; faibha yegirazi inodzivirira kupisa kwakanyanya; faibha yegirazi inodzivirira alkali; faibha yegirazi inodzivirira acid; faibha yegirazi yakajairika (ichireva faibha yegirazi isina alkali uye yepakati-alkali); faibha yemaziso; faibha yegirazi isingachinji ine dielectric yakaderera; faibha inodzora, nezvimwewo.
