• Ungapikisa tembiricha kuchinja.
• Mwando nemishonga.
• High simba nokuda pamberi akaturikidzana.
• Nyore kushandisa (inogona sawn, akachera, uye zvichingodaro. D.).
• It absorbs ruzha.
• It anoshumira paiva kuputira.
• The huni akaiswa mushonga wokuuraya dzinongoitika nebwe, izvo zvinoita mashoko husingakwanisi nokuvhuvha chakuvhe.
• Quite husingakwanisi hasha vezvenhau.
• Nemachira akanaka nokuda vakaratidzawo huni mamiriro.

plywood kugadzira nzira

Kune nzira nhatu:

1. Activities. Huni ukanyatsotarisisa unotemwa kupinda rinoparadza 5 mm paukobvu. In nzira iyi uneconomically vapera chikafu.
2. Slicing - mari zvikuru nzira kuwana 3.5 mm gobvu ukanyatsotarisisa.
3. Peeling ukanyatsotarisisa matanda - nzira umo akagadzirira ukanyatsotarisisa Ukobvu 1,2 kusvika 1.9 mm.

Chii nani plywood: Birch kana softwood?

Siyana anogona kushandiswa pakugadzira mhando huni: nemipaini uye hardwoods. The ehupfumi emashoko kuvimba Chokwadi, kubva mbishi zvinhu. Mumwe mhando ine mikana ayo uye nekuipira.

Softwood plywood rinoumbwa vashomanana akaturikidzana. Material rakagadzirwa larch, Kunogara, vakashinga uye abrasion nemishonga. Kuti uwane yakasimba zvinhu nani kusarudza Birch plywood.

Veneers pamusoro Birch une vakareruka mumvuri uye magadzirirwo havaratidzi akaratidza. Conifers nekusiyana, zvasviba uye watenga raidudzwa muenzaniso.

Coniferous huni akaiswa mushonga wokuuraya dzinongoitika Inogadzirwa nemasiridzi anobuda mumiti. Nokuda kwaizvozvo, zvinhu kubva kwavari zvishoma vachibatwa nokuvhuvha notumwe. Coniferous plywood - iri hwakanaka kokupata chivakwa zvinhu.

chokuguma

The chatingatevedzera zvinhu kunobva namira yaishandiswa kubatanidza ukanyatsotarisisa akaturikidzana. Zvichienderana ichi softwood plywood ane nyora dzakawanda:

• ABF - yakaderera iri kunaka muchiso. Zvinonzi kugadzirwa muchishandisa albuminkazeinovogo namira. Kuti anoita zvinhu zvakatipoteredza noushamwari. Asi hunyoro zvinhu zvakadaro haana angakudzivisai. Rinoshandiswa chete apo hapana kudzivirira mvura.

• FSF - inonyanya kufarirwa muchiso, akaita kushandisa phenol formaldehyde guruu. Hazvina rakasimba zvikuru uye mvura nemishonga.

• PSF-TV yakasiyana kubva FSF muchiso impregnation retardants. Nokuda kwaizvozvo, kwakadai softwood plywood ane murombo combustibility.

• FC akaita kushandisa urea guruu, izvo zvinoita kuti zvinhu zvikuru hygroscopic. Inoshandiswa kugadzira fenicha, kavha, zvinorwisana zvivako.

• SE Water nemishonga haina pachena kuti zvehasha ezvinhu. Rinogona kushandiswa kunyange pasi mvura. Izvi zvinoitwa unobva akaturikidzana ose guruu uye akaiswa mushonga wokuuraya bakelite chete varnish.

• BS - avhiyesheni plywood, iro akawana zita raro nokuda kwayo kushanda mu avhiyesheni uye shipbuilding. Bakelite ukanyatsotarisisa glued doro-soluble guruu. Softwood plywood wokupemberera ichi isapinda, Zvinokosha zvakaisvonaka, kuchinja uye husingakwanisi nehasha vezvenhau.

• BV ane chete ehupfumi kwakaita BS. Musiyano chete ndechokuti mashoko ari chokuguma kutya mvura (akaita kushandisa mvura soluble namira).

Ose plywood yakasiyana pamusoro painoperera. Zvichienderana ichi, zviri nezvezvikwata matatu: unpolished (NSH), pamwe chete-mativi kukuya (SH1) uye pasi kubva kumativi maviri (R2).

PSF

Softwood plywood WBP ndiyo inonyanya kufarirwa pakuvaka dzevagari uye maindasitiri zvirongwa. kurwisa Its kuti mvura iri nokuda impregnation akaturikidzana havaratidzi soluble formaldehyde Inogadzirwa nemasiridzi anobuda mumiti. Mushure impregnation, ukanyatsotarisisa akaturikidzana rakacheturwa pasi muchina pane mukuru tembiricha.

GOST kunogamuchirika yavaive zvimwe kwazvo formaldehyde uye phenol yeimwe. Izvi zvinoomesa kushandiswa plywood zvakananga mumba.

PSF plywood machira vane mwero kukura :. 1,22h2,44 m, 1,25h2,50 m, 1,525h3,050 m, M 1,525h1,525 panguva ukobvu zvichisiyana mukati 4-30 mm.

rave richishandiswa Softwood plywood WBP chiratidzo nevakawanda. The chikuru mirayiridzo kushandiswa ayo:

• Temporary hurongwa panguva kuvakwa.
• Zvivako sheathing.
• The bindepinde pasi pedenga.
• Paivakwa motokari, motokari uye midziyo ganda ravo.
• Kuti vagadzire bindu uye mubindu midziyo.
• Nokuti pakuvaka formwork (uye zvinhu zvinogona kushandiswa kakawanda).
• Somunhu mbishi mashoko pagadzirwe zvimwe zvinhu.

Plywood - chipa uye yepamusoro chivakwa zvinhu, izvo nevakawanda pamisika kwenguva refu.
