Fiberboard: chii ichocho, uye sei mashoko aya anoshandiswa?

Mukugadzirisa uye kuvaka dzimba, zvinhu zvizhinji zvinoshandiswa, asi kune vamwe pakati pavo vakazvifukidza nemukurumbira usina kukwana. Tora, somuenzaniso, fiberboard. Chii ichocho?

Zita rinomirira "fibreboard." Ichi chinyorwa, icho chinobudiswa nekufambisa matanda matanda pamwe nekuwedzera kwemarudzi akasiyana-siyana ezvisungo.

Sokutonga, kushandiswa kwema polymer resins kunoshandiswa mukugadzirisa kwekupedzisira. Mukuwedzera, inosanganisira zvinhu zvakasiyana-siyana zvinopa hydrophobicity properties kusvika kumashoko akapera.

Iyo inodhura zvikuru (uye naizvozvo inowanzoshandiswa) ceresin neparini. Kazhinji kuumbwa kwakawedzerwa antiseptic additives. Nemhaka yeivo, chiganda hachiri kukura pane fiberboard. Chii ichocho? Kazhinji kazhinji mubasa rezvinyorwa izvi zvinoputika zvinonzi phenols, izvo zvinobudirira kudzivisa kufambiswa kwefungi uye kuparadza spores avo.

Wood-fiber plates inobudiswa nenzira mbiri: yakaoma uye yakanyorova. Zvisinei, munguva pfupi yapfuura pane nzira dzepakati: mvura-yakaoma uye yakasviba-yakaoma.

Nzira yakaderera ndiyo yakaoma, iyo fiberboard (chii ichocho, isu tatozvitaura) inoumbwa kubva mumatanda chipi mumamiriro ezvinhu chaiwo uye pasina kuinyorova nemvura. Kufuridzira kwebhodhi kunoitwa pahutano hwepamusoro nekudzvinyirira.

Nyaya inogadziriswa inoratidzirwa nekudhura kwemazana, yakawanda porosity uye chiedza. Utsi hwaro hwemhepo hunongova 6-8% chete.

Nzira yakadzika iri mumatanho akafanana, asi huni dzehuni dzinotumirwa kune kudzvinyirira, kusvibiswa nemvura. Mushure mokusiya mukamuri rekudhinda, zvinhu zvacho zvakatemurwa kuva mahwendefa akasiyana uye zvinotumirwa kune wakaoma. Nzvimbo dzakadaro dze fiberboard dzine chando chiripo mukati ma70%. Nokuti ivo vane simba rakanyanya, asi vanoramba vakasimba.

Nzira iyo yakaoma-yakaoma yakafanana neyokutanga nzira, iyo inotsanangurwa pamusoro apa. Misiyano bedzi ndeyokuti vasati vadya kune chidimbu, zviputi zvinonwiwa, kuitira kuti hunyoro hwehupfumi huve 16-18%.

Iyo nzira yakaoma-yakaoma inopesana nezvose zvataurwa pamusoro apa, yekutanga, ndiro yakaumbwa kubva mumvura yakabatanidzwa nemvura, zvino inodyiswa kune miti yekuoma uye chete inotumirwa kune inotyisa yekuita. Chigumisiro chacho ndeche fiberboard plywood nehukama hwehuwandu hwe 0%.

Cherechedza kuti hatiiti zvakanaka kana tichitaura nezve "shavings". Ichokwadi ndechokuti kuveura, nekubatsirwa kwemichina yakasarudzwa, inotanga kuiswa mukati mehutanda, kubva pane iyo yakagadzirwa mapepa akapedzwa.

Mumakore achangopfuura, fiberboard yakanatswa yakashandiswa kakawanda. Paunenge uchigadzira mapeji akadaro, kupfeka kwakawanda kunoshandiswa kumusoro. Pachigamba chekutanga, ndiro iri yakafukidzwa nechimwe chinhu chinonzi primer layer, icho chinoumba hwaro hwechokwadi. Inonyora chinyorwa simulating inowanikwa pamusoro pemuti.

Iplate yakadaro inenge isingatyi kunyorova, uyewo kubra. Kuti uomesa musoro pamusoro penyaya iyi, rakakosha rinoshandiswa.

Saka takakuudza nezveDVP. Chii, iwe zvino unoziva. Nemhaka yezvinhu zvisingabatsiri uye simba remashoko aya, zvinowanzoshandiswa kwete chete mumashini yemafambisi, asiwo mumhizha yekuvaka.
