下面我們就帶大家了解一下濟南紙箱廠對紙箱包裝壓縮的影響因素。
Next we will take you to understand the impact of Jinan carton factory on the compression of carton packaging.
應力測試過程分為四個階段:
The stress testing process is divided into four stages:
一是預壓階段,保證紙箱與壓板接觸;二是水平壓力線壓下階段,此時荷載略有增加,變形變化較大;三、是紙箱側壁受壓階段,在加載加速度時刻,變形緩慢增加;第四是紙箱完全破損,目前為濟南紙箱包裝破碎點。
The first is the pre pressing stage to ensure the contact between the carton and the pressing plate; the second is the horizontal pressure line pressing stage, when the load increases slightly, the deformation changes greatly; the third is the compression stage of the side wall of the carton, when the loading acceleration occurs, the deformation increases slowly; the fourth is the complete damage of the carton, which is currently the breaking point of the packaging of Jinan carton.
影響蔬菜包裝紙箱抗壓強度的主要因素如下:
The main factors affecting the compressive strength of vegetable packaging carton are as follows:
1. 濟南紙箱包裝是由多層紙組成,合理的紙的組合是保證紙箱抗壓強度的基本條件。
1. Jinan carton packaging is composed of multi-layer paper. The reasonable combination of paper is the basic condition to ensure the compressive strength of the carton.
經過各級紙張物理性能的測試,我們可以開始計算紙箱的抗壓強度,然后經過抗壓強度的計算,生產過程中的各個工序對紙箱的抗壓強度進行控制。
After testing the physical properties of paper at all levels, we can start to calculate the compressive strength of cartons, and then control the compressive strength of cartons in each process of production through the calculation of compressive strength.
2 .紙圈的抗壓強度是保證紙箱抗壓強度的關鍵,但紙張的其他物理功能也不容忽視。
2. The compressive strength of paper ring is the key to ensure the compressive strength of cartons, but other physical functions of paper can not be ignored.
紙,特別是取芯紙抗張強度不好,霽”南紙箱包裝壓縮測試將顯示值的力和變形一直在穩(wěn)步上升,更終價值是非常高的和有效的能源價值非常低,盒子測試后變形如accordion-shaped狀態(tài)。的防水性能也是非常重要的,尤其是冰箱的防水功能要求較高,有時雖然紙箱的抗壓強度非常高,但由于本文不是防水的,簡單的紙箱貼在冰箱里吸收水分,崩潰的形成。
The paper, especially the core paper, has poor tensile strength. The compression test of Ji "South carton packaging will show that the force and deformation of the value has been rising steadily. The final value is very high and the effective energy value is very low. After the box test, the deformation is like the accordion shaped state. The waterproof performance of the refrigerator is also very important, especially the waterproof function of the refrigerator. Sometimes, although the compressive strength of the cartons is very high, but because this paper is not waterproof, simple cartons are pasted in the refrigerator to absorb water and collapse.
3.紙箱的生產過程也會影響其抗壓強度。
3. The production process of cartons will also affect their compressive strength.
通過實驗發(fā)現,在相同的條件下,紙箱的抗壓強度降低了90N ~ 130N,紙箱水平壓力線每加寬1mm,紙箱變形量增加約2mm。壓力線太寬,會在壓力試驗中形成濟南紙盒包裝時力值增長緩慢,有效能值很小,更終變形。為了保證紙箱的抗壓強度,我們應該嘗試改進生產工藝,減少各個工藝對紙箱抗壓強度的影響。
Through the experiment, it is found that under the same conditions, the compressive strength of the carton is reduced by 90N ~ 130n, and the deformation of the carton increases by about 2mm every 1mm of the horizontal pressure line of the carton. If the pressure line is too wide, the force value will increase slowly, the effective energy value will be very small, and the final deformation will occur. In order to ensure the compressive strength of cartons, we should try to improve the production process to reduce the impact of each process on the compressive strength of cartons.
4. 根據紙箱選擇合適的凹槽也很關鍵。
4. It is also crucial to select the proper groove according to the carton.
在人們的理解中,往往認為凹槽越大,紙箱的抗壓強度越高,容易忽略凹槽對變形的影響。角度越大,紙箱的抗壓強度越大,變形越大;凹槽越小,抗壓強度越小,變形越小。如果紙箱太大,但凹槽很小,紙箱在壓力測試中很容易被壓碎;紙箱太小,但凹槽很大,變形太大,緩沖過程太長,有效能值和更終力值偏差太大。
In people's understanding, it is often believed that the larger the groove, the higher the compressive strength of the carton, and it is easy to ignore the influence of the groove on the deformation. The larger the angle is, the greater the compressive strength and deformation of the carton will be; the smaller the groove is, the smaller the compressive strength and deformation will be. If the carton is too large, but the groove is small, the carton is easy to be crushed in the pressure test; if the carton is too small, but the groove is large, the deformation is too large, the buffering process is too long, and the deviation between the effective energy value and the final force value is too large.
5. 水分對紙箱抗壓強度的影響不容忽視。
5. The influence of moisture on the compressive strength of cartons should not be ignored.
蔬菜包裝廠家生產環(huán)境、儲存環(huán)境、使用環(huán)境、氣候、氣候等因素都會對紙箱含水量產生影響,為了保證紙箱的抗壓強度,應盡量防止外部環(huán)境對紙箱含水量的影響。
The production environment, storage environment, use environment, climate, climate and other factors of vegetable packaging manufacturers will affect the moisture content of cartons. In order to ensure the compressive strength of cartons, we should try to prevent the impact of external environment on the moisture content of cartons.
