Luka polima-mchenga: maonekedwe, mitundu ndi specifications

Pomanga nyumba ndi zofunikira chinthu koyamba, mwayi umene uchitika mu mawonekedwe a zitsime wapadera. Iwo amakulolani momasuka kufika ambuye zida chifukwa tikukonza ake yake ndi kuwonongedwa kwa zolephera. Kawirikawiri lotulukira amenewa anali chatsekedwa lids pulasitala zitsulo, koma zaposachedwapa akupitiriza ntchito zimaswa polima-mchenga kwa cholinga ichi. Tiyeni tione chimene chimapanga mankhwala nanga tingachidziwe chachikulu.

kufotokoza mwa chidule

polymeric hatches luso kupanga zachokera njira kuponyera ndi wosachedwa kukanikiza zigawo zikuluzikulu zonse za chuma (mchenga, ma polima thermoplastic, ndi utoto). Njira imeneyi kupanga zimathandiza kupeza mankhwala amene ali ndi ntchito chimbuzi, ndipo ali ndi maonekedwe zooneka.

mankhwala otere ntchito mu misonkhano ya m'matauni madzi, kachitidwe Kutentha ndi makampani msewu. Mu zikuluzikulu yomanga payekha ndi pomanga kuchimbudzi chidzenje amagwiritsidwanso ntchito mchenga ndi utomoni. GOST 3634-99 ndi ukhondo ndi zachilengedwe malamulo, amene adapanga mankhwala, anapereka miyeso yeniyeni ndi khalidwe zoyambirira za chotsirizidwa. Pachifukwa ichi, wogula alibe vuto kuchotsa chimakwirira ndi mankhwala ndi otetezeka kwathunthu kwa chilengedwe.

Ubwino waukulu ndi kuipa kwa mankhwala

Luka polima-mchenga anapatsidwa nambala ya makhalidwe abwino zimene zimachititsa ogula. Njirazi ndi monga:

• mtengo wotsika;
• moyo wautali (zaka 50);
• luso kupirira kwambiri kulemera;
• tisaletse zipangizo zoyendera;
• kukana kuti cheza ultraviolet;
• chomasuka unsembe (popanda kugwiritsa ntchito zipangizo zina zapadera);
• chilengedwe waubwenzi;
• kukana kuti dzimbiri;
• kukana kuti kusintha mwadzidzidzi kutentha;
• kuwala kulemera;
• kusankha zosiyanasiyana mitundu.

Ngati ife kulankhula za zolakwa, amene wapatsidwa mankhwala, ndiye tisaiwale kuti mitundu ina zisoti amenewa anapangidwa kuti katundu yaing'ono. chochitika ichi salola kuti ntchito m'misewu kumene katundu zoyendera ulendo. Komabe, vuto mosavuta anathana ndi kusankha mosamala hatches, kutenga nkhani malo a ntchito.

Polymeric hatches mitundu

Choncho, muyezo waukulu kusankha chipangizo ndi katundu chingathe kupirira polima-mchenga zimaswa. Kulemera kapangidwe ndi chizindikiro chachikulu cha mphamvu: apamwamba ndi, mphamvu za mankhwala. Pa chizindikiro ichi hatches anawagawa makalasi 5:

• kutayipa "L" (munda zosiyanasiyana);
• kutayipa "L" (kuunika);
• Lembani "C" (otsika);
• Lembani "T" (lolemera);
• kutayipa "TM" (lolemera, thunthu).

Hatches amalembedwa kuti "L" (pabwalo) ndi otsika kulemera (25 kg) ndipo amatha kupirira katundu wa osapitirira 1500 kg. Nthawi zambiri iwo amene anaika pa msewu ndi kapinga.

Zamgululi "L" (kuunika) angalemere pafupi 45 makilogalamu ndi katundu makilogalamu 3000. Iwo anapangidwa kuti unsembe m'mapaki galimoto, pa oyenda ndi malo wobiriwira.

Luc (polima-mchenga), ndi "C" kalasi akhoza kulimbana katundu kusalekerera zolimbitsa (7500 kg), pamene ake kulemera ndi 52 kg. Mbali ya mamangidwe - m'mapaki mzinda wa magalimoto zambiri, msewu.

katundu katundu (gulu "T") akhoza kale kuikidwa pa misewu kumene magalimoto zolimbitsa. kulemera ndi makilogalamu 57 ndi pazipita katundu - 15000 kg.

Chachikulu hatches waukulu angathe kupirira mpaka 25,000 makilogalamu katundu, kotero iwo angagwiritsidwe ntchito pa msewu uliwonse. Unyinji wa chimakwirira ngati - makilogalamu 60.

Kupatula kusiyana katundu, polima hatches osiyanasiyana mawonekedwe. Nthawi zambiri opangidwa chivundikiro zozungulira (chifukwa chakuti wanga mobisa zitsime zambiri kuzungulira), koma kupanga mankhwala lalikulu-n'zothekanso (pa pempho).

miyeso

Kusiyana kwina pakati pa malonda a magulu osiyana ndi m'mbali, omwe mwina polima-zimaswa mchenga. Makulidwe a chimakwirira komanso amadalira mlingo wa kusalekerera awo. Kuwala kutentha chivundikirocho ndi awiri a 600 mamilimita ndi kutalika kwa 25 mm, ndi casing kapangidwe lokha pang'ono mowonjezera (720h60 mm).

Gulu M'mapapo hatches yodziwika mm kukula 690h55 ndi 750h90 mamilimita chivindikiro kwa thupi. Nkhanizi kupirira katundu sing'anga ndi miyeso 690h50 mm (chivindikiro) ndi 750h100 mm (nyumba). Kukula mitundu ya akwaniritse 700h70 mm. Mlanduwu miyeso analimbitsa nyumba - 800h110 mm.

ogwiritsa

Unsembe wa mitundu yosiyanasiyana ya mankhwala polima alinso ndi makhalidwe yake. Choncho, polima-zimaswa mchenga kuwala mtundu yakwera pa akuya 25-45 mm, ndi kapangidwe sekondale yokoka - 60 mm. Wamphamvu kuposa onse chinakula hatches lolemera - iwo ali wokwera pa 85 mamilimita kupita pansi.

The ndondomeko unsembe akuyamba ndi polima dongosolo kukhazikitsidwa mphete (pa slab konkire). Kabukuka kali ndi matope simenti ndi analola kuti ziume kwathunthu. Kenako, mbuye amapereka zimaswa chivundikiro yokha.

Padziko bwino (ndi otsetsereka pang'ono) yothetsa m'dera akhungu. Iwo anafunika kupewa malowedwe a chinyontho mu posungira. M'lifupi mwa malo akhungu zambiri zimasiyanasiyana mamita 1 1.5. Kwakukulu ntchito ndondomeko ya khazikitsa ndi zimaswa akhoza kugula mankhwala ndi mipata wapadera mindandanda yamasewera.
