Maitiro eRTM ane zvakanakira zvekuchengetedza zvakanaka, kugadzirwa zvakanaka, styrene isingatsvedzereki zvakanyanya, kunyatsojeka kwechigadzirwa uye mhando yepamusoro kusvika padanho repamusoro regiredhi A.
Maitiro ekuumba RTM anoda saizi chaiyo yemold. rtm inowanzo shandisa yin ne yang kuvhara mold, saka kukanganisa saizi yemold uye kudzora kwakarurama ukobvu hwegomba mushure mekuvhara mold inyaya huru.

1, Kusarudzwa kwezvinhu
Kuti chiumbwa chive chakanyatsogadzirwa zvakanaka, kusarudzwa kwezvinhu zvakagadzirwa chinhu chakakosha. Kugadzirwa kweRTM moldIyo inoshandiswa mujasi rejeri remuforoma inofanira kunge yakasimba, inodzivirira kupisa zvakanyanya uye yakaderera shrinkage, uye inogona kushandiswawo mujasi rejeri remuforoma revinyl ester.
RTM mold resin inowanzodawo kuramba kupisa zvakanaka uye kuomarara, kuomarara kwakati wandei, shrinkage idiki kana kuti iri pedyo ne zero shrinkage. MaRTM mold ane fiber reinforcement materials anogona kushandiswa 30g / ㎡ non-alkali surface felt uye 300g / ㎡ non-alkali short-cut felt. Ne 300g / m non-alkali short-cut felt pane 450g / m non-alkali short-cut felt yakagadzirwa ne mold shrinkage yakaderera, ine divi rakakwirira rekururama.

2, Kudzora maitiro
Kusarudzwa kwezvinhu zvakagadzirwa ndekwekudzora saizi yeRTM mold uye ukobvu hwechinhu chakakosha chinongedzo, uye mukuita kwekutendeuka kwemold chero nguva kudzora mhando inzira inonyanya kukosha. Kana kudzora uku kusingakodzeri, kunyangwe kana zvinhu zvakagadziriswa zvichisangana nezvinodiwa, zvakaoma kutenderedza mold nehukuru hwakarurama uye ukobvu hwemota hwakakodzera.
Maitiro ekushandura mold anofanira kutanga anzwisisa kunyatsojeka kwemold yehuni inoshanduka. Kuti ive nechokwadi chekuti yakanyatsojeka, pakutanga kwesefa dhizaini yehuni inogona kushandiswa zvichienderana nehuwandu hwekudzikira kwemold kuti isiye huwandu hwakati hwe shrinkage allowance. Pamusoro pezvo, kutarisisa kunofanirwa kupihwa pakuchinjika kwepamusoro pehuni inogadziriswa, mavanga ehuni pamusoro pemold anofanira kucherwa. Mavanga uye kudzikira kwehuni hakuenderane kuchaita kuti pamusoro pemuchina we fiberglass udzike. Chera mavanga uye bvisa maburi epamusoro, pamusoro pemuchina wehuni unofanirwa kukwenywa putty treatment, kazhinji inodiwa kukwenya ka2-3. Mushure mekunge putty yapora, shandisa sandpaper kupukuta pamusoro kusvika yasangana zvizere nezvinodiwa zvehukuru nechimiro.
Kugadzirwa kweforoma yemapuranga kunofanirwa kunge kwakagadzirira kushanda nesimba, nekuti kazhinji, kururama kwehukuru hweFRP mold pakupedzisirazvinoenderana nekururama kwechimiro chehuni. Kuti uve nechokwadi chekuti pamusoro pechinhu chepurasitiki chakasimbiswa nefiber yegirazi chakatsetseka uye chakachena, tendeudza chidimbu chekutanga chechinhu chepurasitiki chakasimbiswa nefiber yegirazi, gel coat layer uchishandisa nzira yekupfapfaidza ndiyo yakakodzera.
Gelcoat yekupfapfaidza inofanira kunyatsoteerera kugadzirisa kufamba kwemhepo yepfuti, kuitira kuti gelcoat resin atomization ive yakafanana, isaratidze zvidimbu. Pfuti yekupfapfaidza nepfuti zvinofanira kunge zviri kunze kwemold, kuitira kuti isakonzerese kuti gel coat yemuno irambe yakaturikwa, zvichikanganisa kunaka kwenzvimbo. Mushure mekunge gel coat layer yagadziriswa, namatidza surface felt. Surface felt inofanira kunge iri kunze kwemold, kuitira kuti isakonzerese kuti gelcoat yemuno irambe yakaturikwa, zvichikanganisa kunaka kwenzvimbo.
Mushure mekunge jira rejasi rapera, namatidza pamusoro pejasi, jira rejasi rinofanira kuvharwa nejira rakati sandara, rakapetwa kana kuti rakakotama rinofanira kuchekwa uye kuchekwa. Namatira pamusoro pejasi rakanaka, bhurasho rinogona kunyikwa mu resin diki kuti rinyure pamusoro pejasi, teerera kudzora huwandu hweglue, zvese kuti zvikwanise kupinda mukati me faibha zvizere, asi kwete zvakanyanya. Guruu rakawanda, bubble harisi nyore kubvisa, uye rinokonzera kupwanyika kukuru, kwakakura. Surface felt layer resin inoporesa kuti itore mabubble, pick bubbles haigoni kucheka ne gel coat layer.
Mushure mekutora mabubbles, bvisai sanding yakakodzera, bvisai fiberglass burrs mobvisa guruva rinoyangarara, gadzirai 300g / m² non-alkali short-cut felt, nguva imwe neimwe 1 ~ 2 layers ye paste, kuti irapwe mushure me exothermic peak usati waenderera mberi nekunamira. Namatirai kusvika pakukora kunodiwa, munogona kuisa copper pipe, moisa insulation core block. Modulation yegirazi beads resin putty, sekuisa thermal insulation core block adhesive, iyo yekuzadza gap pakati pe thermal insulation core block.
Mushure mekuisa, girazi remachira rinofanira kushandiswa kukwesha mukaha uri pamusoro pechivharo chepakati chekudzivirira kuputira. Chivharo chepakati chekudzivirira kuputira wobva wanama zvidimbu zvitatu kusvika zvina zvefelt pfupi-yakachekwa, unogona kunamira skeleton yesimbi yemuumbi. Namatira skeleton yesimbi, skeleton yesimbi inotanga yanamirwa kubvisa kushushikana kwewelding, uye skeleton yesimbi nemukaha uri pakati pechivharo zvinofanirwa kuzadzwa kudziviriraFRPkuchinja kwechimiro nesimbi.
Mushure mekunge chidimbu chekutanga chemold charapwa, mold inobviswa, mupendero wakawandisa unobviswa, mupendero wemold unobviswa marara, uye wax sheet inoiswa. Ukobvu hwewax sheet inoshandiswa hunofanira kunge hwakafanana uye kureba kwayo kunofanira kunge kudiki. Wax sheet haifanirwe kuputirwa nemabubble emhepo, kana paine mabubble emhepo, inofanira kubviswa yonamatwazve kuti ive nechokwadi chekuti mold iri kukura. Mapazi emupendero anofanira kuchekwa, uye mipata iri pakati pewax sheets inofanira kuenzaniswa neputty kana rabha simende. Mushure mekunge wax sheet yaiswa, mold yechipiri inogona kutenderedzwa nenzira imwecheteyo nemold yekutanga. Mold yechipiri inowanzogadzirwa mushure mekunge gelcoat yapfapfaidzwa, uye maburi ejekiseni nemaburi emhepo zvinofanirwa kurongwa. Tendeudza chikamu chechipiri chemold, unofanira kutanga wabvisa mupendero unobhururuka, weld mapini ekuisa uye makiyi ekuvhara, kuti unyatsopora mushure mekubviswa.

3, Kuongorora Mould uye matanho ekugadzirisa
Mushure mekudzima nekutsvaira, shandisa simende yerabha kuyera ukobvu hwegomba remould. Kana ukobvu nehukuru zvichigona kusangana nezvinodiwa, mushure mekunge nzira yekukuya nekupukuta yapera, mould yeRTM ichapindurwa zvinobudirira uye inogona kuendeswa kukugadzirwa. Kana bvunzo, nekuda kwekudzora kwakashata kwemaitiro nezvimwe zvikonzero zvinokonzerwa negomba remould ikasasangana nezvinodiwa, tsvina, kuvhurazve mould zvinosuwisa zvikuru.
Zvichienderana neruzivo, panogona kuva nemhinduro mbiri:
1. Ndakabvisa chimwe chezviumbwa, ndikavhurazve chidimbu;
② kushandisa maitiro eRTM pachawo kugadzirisa hunhu hwechiumbwa, kazhinji chidimbu cheganda reganda reganda chinobviswa, chakaiswa pamusorogirazi rakasimbiswa nefaibha, chimwe chidimbu chechiumbwa chinonamirwa papepa rewakisi, gelcoat inopfapfaidzwa, uye jekiseni rechiumbwa, rinozorapwa mushure mekugadziriswa kwechiumbwa, rinogona kuendeswa kunoshandiswa.
